colour depends on wavelength or frequency??reply wid a good proof..?

Answer 1

Wavelength, not only colors are determined, you are possibly thinking of the visible spectrum, colors are only a very small portion of electromagnetic waves ranging from gamma rays to radio waves. the colors are determined by the frequency of those waves ranging from the shortest wavelength about 400nm (Violet) to the longest about 650 nm (red) Ultraviolet and Infrared are outside the visible spectrum of humans and cannot be seen by us. The colors of the visible spectrum and their corresponding wavelengths are as follows.

Violet ~ 400nm
Indigo ~ 445nm
Blue ~ 475nm
Green ~ 510nm
Yellow ~ 570nm
Orange ~ 590nm
Red ~ 650nm

Answer 2

Energy is what we see as color. Low energy levels look red, high energy levels look blue or violet. All the other colors lie somewhere in between on the color spectrum.

E = hf for EM forces, like light. h is Planck's constant and f is the frequency of the EM packet of energy called a photon. fL = c; where L is wavelength and c is the speed of light, which is a constant for any given medium.

Thus f = c/L; so that E = hf = hc/L Thus, since color is how we see the energy levels, then it clearly depends on frequency or wavelength since they are interchangeable. QED.

Answer 3

Frequency directly varies with wavelength. Frequency = Speed of light / wavelength.

Answer 4

Both .
You would usually find relationships of colurs with wavelengths

But wavelength * Frequency = Velocity of light in vacuum ( c)

Since velovity of light is constant in vacuum
Wavelength = c / frequency

Thus wavelength is inversely proprtional to frequency.

Answer 5

They are interchangeable... wavelength = c / frequency
where c is speed of light in vacum.

you may say it depends on wavelength or frequency

Answer 6

wavelength and frequency are the same thing. so color must depend on the perception of the eye of the beholder. what color is red

Answer 7

The frequency. The wavelenght depends also on speed of light.
