Visible Light Spectrum

Energy of photon increases.

frequency energy wavelength

Yes. Every different frequency (wavelength) of light is perceived as a

different color by the human eye. Except in colorblind people, that is.

Take a lightbulb so the bottom touches on end of a battery.

Take a wire and touch the battery and the other end to the lightbulb.

That's one I've never seen. Does the bathroom light turn ON when the bedroom light is switched Off?

Does the bathroom light switch turn the bathroom light on and off normally when the bedroom light switch is left on? Need to answer these questions, then find where the bathroom light power comes from. It's power supply should either go directly from the power oanel to the bathroom light or to the bathroom light switch. The bathroom light switch merely acts as an interrupter for the hot leg of this power supply.

Visible light is a small part of the electromagnetic spectrum.

No!! Light beams of photons do not interfere with one another except in crystals as phonons.

There's no 'range'. The speed of any electromagnetic signal, including light,

is 299,792,458 meters (186,282 miles) per second in vacuum, somewhat

slower in any material, depending on the material, regardless of wavelength.

Our eyes cant perceive motion faster than 1/10 of a second and light can travel about 10,000m in 1/10seconds. Since a normal room is on an average 7m x 7m, there is no observable delay in between turning on a light and seeing the emitted light.

it should be 3x10^8 m s^(-1). here is the calculation:

we have known that the refractive index of vacuum is 1,

by n= v/c ( n stands for refractive index of medium, v stands for the speed of light in medium, c stands for speed of light constant)

1=v/3X10^8 m s^(-1)

v=

therefore, speed of light in vacuum is 3x10^8 m s^(-1)

actually, all light ray in electromagnetic spectrum have same speed in vacuum

Because the visible light coming from the stars is so faint that during the day the light form our local star (the Sun) is so bright that it swamps the starlight.

Thus to make observations using visible light, astronomers have to do so at night.

A comet emits no light of its own, until close enough to be

illuminated and stimulated by radiation from the sun.

Moving up the electromagnetic spectrum will reveal increasingly more energetic (higher frequency and shorter wavelength) radiation. These higher energy types of radiation have a greater ability to penetrate (and damage) tissue.

Comets get brighter the closer they get to the sun for two reasons: the sunlight is brighter closer to the sun than it is further away and the comet heats up closer to the sun causing outgassing and the formation of a large coma composed of dust particles and gas around the comet itself giving a much larger area for sunlight to reflect off of.

Violet. Recall VIBGYOR. Violet at the high frequency extreme and Red is at the low frequency extreme

If both of them are in the same substance, then their speeds are equal.

The pigments involved (e.g. chlorophyll in green plants, phycoerythrin in red algae) only absorb photons of certain energies and reflect others. This is due to the elements in the pigment molecule and how they are bound.

refractor

Because it penetrates the skin and can cause mutations.

The most visible color in the spectrum that promotes plant growth is blue light. This wavelength of light is crucial for the process of photosynthesis, which plants use to convert light energy into chemical energy. Blue light helps regulate plant growth, leaf development, and flowering.

laser light is produced by solar reacting pannels that are transfered into capsules that contain magna light that turn into a small red flash of light.

Electromagnetism is manifest along a continuum between slower radio waves and faster energy gamma waves. Visible light can be found in the range between infrared light (slower than waves of visible light) and ultraviolet light (faster than waves of visible light).

AM radio, FM radio, television, cellphones, GPS, and microwave ovens

all use radio waves that are longer than the ones used for RADAR.

Any whose wavelength does not exceed 379 nm.

they are all part of the electro magnet spectrum :)
