SCIENCe wavelengths . Yes, there are. If youre talking about electromagnetic radiation, they have the same speed 3*10 8 They vary in wavelength (greek letter lambda) and frequency to maintain this as speed of light= wavelength * frequency You'll find this in an Electromagnetic spectrum....
v=fλ Visible light is an electromagnetic wave. All electromagnetic waves travel at 3.0x108 m s-1 in a vacuum. Since the question doesn't supply additional info I'm assuming the medium is a vacuum. Hence, v=3.0x108 m s-1 and λ=486x10-9 m. Therefore, f=v/λ = 6.17x1014 Hz
Yes,visible light is used. Frequencies of blue and red absorbed effectively
Rainbows are an optical illusion, they are not "real". You cannot view them from above; they will always appear the way they appear from the ground.
An atom is smaller than a single wavelength of visible light
Jupiter does not produce light. It does, however,  reflect a lot of the sunlight that reaches it's surface. The  amount of light that a planet's surface reflects is call it's  albedo, and it's expressed as a value between 0 (nothing  reflected) to 1 (100% of light is reflected). Jupiter has an...
The wave length of visible light ranges from 400 nm to 700 nm
The rainbow may be very close or very far away. It is seen from the formation around water droplets that can be as close as a few feet to many miles distant.
Yes they are. Rainbows are only an appearance of light when light goes through water. That's why rainbows usually appear after it rains or when it is humid.
I believe you asking if you are right with your facts. Rainbows  happen when sunlight and rain combine in a very specific way. The  beams of sunlight separate into the colors we see in the rainbow as  they enter a raindrop. Sunlight is actually made up of different  colors that we don't usually...
An x-ray telescope. They are far too small to be seen optically.
Upside down rainbows are called circumzenithal arcs. They are not caused by light refracting through water droplets like normal rainbows, the arc is a result of sunlight bending to create a spectrum of colour after reflecting off ice crystals high in the atmosphere. It only appears when...
bright colors of red orange yellow green blue indigo and violet also known as the man Roy G. Biv...keep it happy
wavelenghts of energyNOVANET! It represent different in energy of photon at different colour range. Different wavelength yield different colour whether we can see it or not. The evolution choose this range of light to be visible for abundant of such spectrum range from the sun while some animal can...
Violet, with a wavelenght between 380 and 450 nm, which is near the end of the visible light, next to the ultraviolet region. Be careful because talk about "colors" is quite dangerous. Firstly, different cultures has different names for the same color. In addition to this, due to the fact that the...
The wavelength of a wave (the amount of energy the wave carries) determines its placement on the spectrum of visible light.
Depends what sources of light you call natural or artificial sources. -- I'd call candle light an artificial light, produced by burning refined petroleum products in oxygen. -- I'd call moonlight natural light. It's actually starlight, produced by nuclear fusion in the core of the Sun.
by diffraction. when a light wave hits water or glass, it diffracts into separate waves (colors) due to their different wavelength, the way the sunlight diffracts after raining, giving us rainbows
the colour of the objects which don't reflect any part of visible spectrum is "BLACK". black coloured objects absorb all wavelengths of light
Visible light is between 380 and 750 nm. With lower wavelength you have ultraviolet, X-Ray and gamma-ray. With higher wavelength, infrared, microwave and radio signals.
We know that ultra-violet light, X-rays and gamma rays all have wavelengths shorter than those of visible light.

The Rainbow Warrior was a Greenpeace protest boat. It went to the Pacific Islands that were being nuclear tested on, and protested against it, to make them stop. It was sunk in Auckland Harbour on 10 June 1985 by French Secret Agents.
It a coloured feather. You'll get it when you talk to the old man in Pewter city (Kanto) in Pokemon Gold or Silver. At the Tin tower on the roof there is a Ho-oh there.P.S. Before you 'burst in' and catch the Ho-oh with the masterball, there's a Lugia at the Whirl island.
The next name of wavelengths longer than ultraviolet rays is  "violet light".
  The color of the wavelength lambda = 686.2 nanometers is "deep red". The wavelength lambda = 685 nanometers equals the frequency f = 436,887,872,340,425 Hz.   1 nanometer = 1×10−9 meter.   686.2 nm = 0.0000006862 meters.   Scroll down to related links and look at "Radio and light...
They are both electromagnetic rays and both are produced by stellar objects.
Red is the longest wavelength of visible light
High pressure sodium lamps take a while to fully light up, however they are very energy efficient and save the council money.
Visible light occupies on a VERY SMALL fraction of the electromagnetic spectrum, that is, a very small minority.
Rainbows are created by the rain reflecting the sunshine.
they appear when it is sunny and raining
There is not a pot of gold at the end of a rainbow. If youthought that there was, the isn't. It's just an old tale, and therecan't be a pot of gold at the end of a rainbow because a rainbow isa circle. The other halve that we can't see is invisible.
white light.... , The one that comes from the sun , light bulbs ... and that allows us to see.
nope, but lepricorns can
if it can escape the room it will continue on until it hits and  obsitcle, at which points it disapates on impact due to its speed  and inability to penetrate the object
Visible light only occupies a small part of the electromagnetic spectrum. In the last 150 years people have discovered and put to use a large part of that spectrum. We use it to take x-rays, treat cancer, communicate with satellites, communicate with submarines, and for many other uses. A number of...
Light is very important. Sunlight helps plants grow, we need light to see, and we can't do almost anything without light.
red orange yellow green blue indigo violet
whenever there are water droplets in the air and the sun is shining through them at a low angle. This angle is 40 - 42 degrees from the observers head. If the sun is any higher the rainbow effect will not be seen as the rainbow will be below the horizon. Secondary rainbows can occur at about 50...
They only form at 42 degrees from the direction opposite the sun

It means the bending of light.
Lollipops and Rainbows doesn't have any clothes but Ems has a clothing line at Ooh La La! Couture called the Emily Grace Collection. She also has a line at Three Peas Co. called Emily Grace by Three Peas Co.
Visible light includes any color that the eye can see.
There would not be sufficient heat for plasma to form in a rainbow.
I am only an eighth grader, but read my answer. So, when the visible light passes through the prim and refracts on it's edges, the beam of light splits into a spectrum and it looks like a rainbow, only because white light is acctually all of the colors of light put together. Hope i helped :) A ...
Visible light is part of the electromagnetic spectrum. The visible part has wavelengths of 7000 to 4000 Angstroms. The frequencies are 4.0 - 7.0 x 1014 Hz.
They are measured in terms of a smaller "unit value" to avoid constantly using the decimal or exponential values. That is, it is easier to compare wavelengths if they are expressed as integer values. A nanometer is just a convenient way of saying one-billionth of a meter. Example : Humans can see...
  == Answer ==   A rainbow is curved due to angle requirements. Light from the sun that bounces through a drop of water, comes into your eye, and appears red must bounce at a specific angle. Join two sticks together at a set angle. Place one end at a dot to represent the sun. Place the...
a gathering of boys and girls where each girl puts on a different shade of lipstick and the boys get oral from a group of them, thus leaving a rainbow.
A true "black light" should emit only ultraviolet radiation. Violet light waves have the highest frequency visible to a human eye. Ultraviolet has a higher frequency, and the human eye cannot detect it. When you buy a "black light" at the party store, in addition to the ultraviolet radiation, the...
When you shine white light through a prism, at the correct angle wherever the prism is pointing you will see the spectrum, this is because when the light shines through the angles of the prism, the white light will become dispersed through the angles so that the white light is streched out to reveal...
  We cannot see incident light in the visible light frequency specrum. If we could, we would not be able to discern anything, everything would be a bright fog. All the light we see has been bounced off something on it's way to us. We see the reflection of the visible light frequency spectrum off...
we learned this in science today. the answer is the beginning (where red starts) it is the color red. why im not sure
light takes a straight path.
    Red, Orange, Yellow, Green, Blue, Indigo and Violet! You learn this in Kindergarten genious. From: But-smart
You can use the acronym ROY G. BIV to remember them in order: red, orange, yellow, green, blue, indigo, and violet.
7-red,orange,yellow,green,blue,indigo,violet
a rainbow meebling is a secret meebling in the meeblings 2 game its on level 38 click the blue meebling in the top left corner then you have to click the first yellow meebling that falls in two seconds then click the blue meebling that was in the bottom right corner when you started twice and the...
Short answer:We don't see them because we can't see them. If we could see them then we would be able to see them and the question is irrelevant.More detailed answer:Because seeing is the definition of a process by which a certain range of electromagnetic frequencies strike a portion of any organ...
Because light is being split up through water no matter what.

The separation (dispersion) of white light into it different components (different wavelengths) caused by the light entering into a more optically dense medium, such as rainwater or glass from a less optically dense medium such as as air or a vacuum. Each wavelength or colour is slowed down by a...
  It affects the color of the light. If you change the wavelength of visible light, you change the light's color. For instance. Red is a wavelength of approximately 650 nanometers. Orange, about 590. Yellow, 570. Green- 510, Blue, 475 nanometers. Indigo is 445 and Violet is about 400.    ...
We can split white light by passing it through a prism
With visible light, and the individual's ability to perceive it, comes the constant danger that you might unwittingly be exposed to sights that you don't want to see, or to the sight of things that you would be better off not seeing.
I'm not sure maybe someone else should answer it because it's on my science worksheet
The brightness has nothing to do with it. Colors closer to the violet end have more energy.
Of the three, gamma rays have the smallest waves and the highest frequency.
Visible light falls between the wavelengths of 380 nm and 760 nm in the electromagnetic spectrum.
No. Both travel at exactly the same speed. The speed of light.
The layer in the sun's atmosphere that gives off visible light is known as the Photosphere.
Rainbow in the Greek language is : Ουράνιο τόξο
When white light shines on the CD, the light is separated into seven colours, so different colours appear on the CD.
b'cause of the sunlight falls b/w the droplets & the droplet works like prism it separate the white light in 7 colrs..........
The wavelength of ultraviolet light is between 10 and 400 nanometers (nm).From the wavelength you can determine the frequency. If you divide the speed of light by the wavelength, you can calculate the frequency. The frequency range would be from 7.5 x 1014 Hz to 3 x 1016 Hz.
If you shine a rainbow nto a prism the rain bow will become larger like 2x the original rainbows size. 8^)
