Why white light colours have different speeds according to their frequencies but not the other electromagnetic waves while all have the same speed of light?
Waelalsallami
Answer: The white colors have different speeds and not other electromagnetic waves because they are not usually consisted by more than one colors like the white colors.
Answer: You are really confusing two different things. (1) In a vacuum, all electromagnetic waves travel at the same speed. That includes light of different colors. They all travel at the so-called "speed of light" - without further qualification, this term means "the speed of all electromagnetic waves in a vacuum", and this speed is approximately 300,000 km/sec. (2) In materials other than a vacuum (empty space), electromagnetic waves get slowed down - and the amount by which they slow down depends on the frequency. Thus, not only light of different colors will be slowed down by different amounts, but also radio waves, ultraviolet rays, etc., if they are able to pass through a material at all. For more information, do some reading - for example, on the Wikipedia - on "index of refraction", and on "speed of light".

What is a Electromagnetic spectrum?
The combination of different colours due to the dispersion of sun light is called spectrum. This type of spectrum is called continues or line spectrum.
What results from wavelengths and frequencies of light and sound?
Different wavelengths and frequencies of light are interpreted as different colours; those of sound are interpreted as pitch.
What is light is it one of the fundamental components of understanding colour?
Different amounts of energy contained in different frequencies cause different colours to be perceived by us. It's all in the spectrum of visible light.
What is the EM spectrum?
The electromagnetic (EM) spectrum is the entire range of frequencies that electromagnetic radiation can have. The EM spectrum is divided into sections based on the common characteristics that certain frequency ranges have. These sections are, in order from low to high frequency, radio waves, microwaves, infrared waves, visible light (which from low to high frequency is further divided into red, orange, yellow, green, blue, indigo, and violet), ultraviolet waves, X-rays, and gamma rays. You can think of the EM spectrum as an invisible rainbow with visible light being a small part of it. And, like a rainbow, the edges of the divided sections are blurry; i.e. there is no exact frequency where one can say, for example, that this wave is no longer an X-ray, but is instead a gamma ray. it is waves of light in order of their wavelengths and frequencies APEX: A chart of frequencies of light waves.
Will prism disperse light in water?
Yes, light always disperses when entering a medium other than vacuum because photons with different frequencies (different "colours") have different velocities in a medium other than vacuum, therefore different angles of refraction.

Does the frequency of light change when it is reflected?
No. Otherwise, we would have seen new colours when light is reflected, since all the colours have different frequencies.
What causes colour?
Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.
What can you say about the speed of different colors in air?
You can that they're all identical.
Why do different colours of white light bend through different angels with respect to the incident beam of light?
Refraction ! The light is made up of different frequencies that bend at different amounts
What is the difference between the colours of visible light?
their wavelengths (frequencies)
Newtons prism experiments showed that white sunlight is made up of?
Electromagnetic radiations which ranged in appearance from red to violet. He did not see beyond the visible spectrum - into the infra red and lower frequencies, nor ultra violet and higher frequencies. It is understood that he initially defined the spectrum as consisting of 4 colours but later, to bring it in line with the musical scales, the spectrum was split into seven colours. The spectrum is, of course, a continuum, consisting not of 4 nor 7 but an infinite number of colours.

Why must there be sunshine and rain in order to for a rainbow to be seen?
The sunlight whenpassing through water droplets in air is refracted into different colours making a rainbow. Sunlight (white light) is composed of visible rays at different frequencies. Different frequencies bend when passing through water at different angles and can be seen separately.
What color rain contain?
Rain doesn't "contain" any colours. Rain is water falling from the clouds while colous are represented by different frequencies of light.
