Visible Light Spectrum

X-rays have the highest frequency in the electromagnetic spectrum.

The shortest wavelength of visible light is around 400nm because this corresponds to the color violet, which has the highest frequency and energy among the visible light spectrum. Wavelengths shorter than 400nm are in the ultraviolet range, which is not visible to the human eye.

Low intensity light composed of long wavelengths in the red-orange spectrum is likely to be infrared light. This type of light is not visible to the human eye but can be felt as heat when directed at an object.

Visible light. It has a higher frequency so more energy.

Rainbows are formed when sunlight is refracted and reflected in water droplets, separating the different wavelengths of visible light. Each color of the rainbow represents a different wavelength of light, showing that sunlight is composed of a range of wavelengths from the entire visible electromagnetic spectrum.

No, ultraviolet light has a higher frequency than visible light. Visible light has wavelengths between about 400 to 700 nanometers, while ultraviolet light has shorter wavelengths below 400 nanometers.

In 1909, Ernest Rutherford fired alpha particles (helium nuclei) at a very thin sheet

of gold foil. Many of the alpha particles passed through but some were deflected

at an angle and some surprisingly bounced back. This experiment showed that the

atom had a dense but very small positive core, the electrons were far away from

the very small positive core (nucleus), and the electrons were separated from the

nucleus by a lot of empty space. The atom is more than 99.999999% empty space!

Like clear glass insulators, it seems that everything should be transparent to visual

light. However, metals have a loose sea of electrons that makes visible light bounce

back and the metal appears shiny. For opaque objects like metals, most of the light

is either reflected by the object or absorbed and converted to heat. For transparent

objects like air and clear glass, the light travels through it.

Another contributor passes through and pauses to observe:

The question is perplexing. It starts off by asserting glibly that insulators ...

which in my experience includes wood, rubber, and concrete ... are transparent

to visual light.

Seems to me that if insulators were transparent to visual light, then we would

always be able to see every conducting wire inside a cable of many wires, since

each and every one is covered in an insulating jacket.

The process responsible for producing visible light in the sun is nuclear fusion. This process involves the fusion of hydrogen atoms to form helium, releasing a large amount of energy in the form of visible light and heat. This ongoing nuclear fusion reaction is what powers the sun and allows it to emit light.

Astronomers study a wide range of electromagnetic radiation besides visible light, including radio waves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays. Each part of the spectrum provides unique information about celestial objects and events, helping astronomers to study everything from the cool clouds of gas and dust in space to the high-energy processes in black holes.

Photon arrival probability refers to the likelihood of a photon reaching a particular point in space within a given time interval. It is used in various fields such as optics, telecommunications, and quantum physics to describe the statistical distribution of photons arriving at a detector or sensor. This probability is influenced by factors such as the light source intensity, distance traveled, and medium through which the photons are propagating.

When light has a higher frequency, it means the wavelength is shorter and the energy of the light is higher. Higher frequency light can have more pronounced effects, such as greater potential for damaging biological tissues and the ability to excite electrons to higher energy levels. Examples of high frequency light include ultraviolet and X-rays.

Red is the lowest. From there, frequencies increase, in the order of the colors

of the rainbow, until you reach the highest visible frequency at violet.

The only part of the electromagnetic spectrum that we can see is the small yet significant part of visible light. Visible light is not harmful for humans, but some of the other types of waves are.

Infrared has a smaller wavelength than microwaves.

High-energy photons correspond to short-wavelength light while low-energy photons correspond to long-wavelength light.

In short, the answer is red.

For short-wavelengths (high energy photons) it would appear blue.

The colors in the electromagnetic spectrum are put in that order based on their wavelengths. Shorter wavelengths correspond to higher frequencies and are seen as violet, while longer wavelengths correspond to lower frequencies and are seen as red. This progression follows the visible light spectrum from shortest to longest wavelengths.

The name for when light is split up into the different colors of the spectrum is called "dispersion."

A primary light source is one that actually produces light, such as a light bulb or the sun.

A secondary light source in one that ONLY reflects the light produced by a primary light source. It doesn't produce light itself, such as a mirror or the moon.

Heat does not have a specific wavelength because it is a form of energy transfer rather than a specific type of electromagnetic radiation like light. Heat is typically associated with infrared radiation, which has longer wavelengths than visible light.

The names we give to a few other wavelength-bands of electromagnetic radiation are:

-- radio

-- microwave

-- heat

-- X-ray

-- gamma ray

After you've spent some time here on Earth, you'll get used to these terms,

and you'll quickly understand what we do with these categories of radiation.

This is to maximize the effect of diffraction. The wavelength of the photon can be regarded as its 'size' . If it is too large then the slit is just to small for it and most of the photons will be absorbed or reflected. If it is far too small then the slit, in comparison, will be very large so most photons do not even notice its presence and will just continue on their merry way without interacting with it.

The true primary colors are red, blue, and yellow. These colors are considered primary because they cannot be created by mixing other colors together.

No, light is not visible to the human eye when it passes through a vacuum because there are no particles in a vacuum to scatter or reflect the light towards our eyes. We can only see light when it interacts with matter such as air, water, or solid objects.
