Various colours of light differ in__________?

Question

A. frequency only

B. wavelegth only

C. their speeds in vacuum

D. frequency and wavelength

Answer 1

D. frequency and wavelength

The speed through a vacuum is constant for all electromagnetic radiation, including all visible light, so the answer is not C.

If the speed is constant and you change the frequency or wavelength then the other has to change as well -- so the answer can't be A. or B.

Answer 2

it is D

coz even visible light have a certain range of the wvalength between 700nm(for red) and 400 nm(for violet) and also a range of frequency between 4.3 x10^14 and 5 x 1^0^15 Hz

Answer 3

D. frequency and wavelength

Answer 4

Its not frequency because all coulors of light are under 'visible light' which all have the same frequency, im guessing its wavelength only or choice B

Answer 5

D frequency and wavelength

Answer 6

The speed of light in vacuum is constant.  The product of frequency and wavelength is therefore also constant.  So as the colour of the light changes so do both its frequency and wavelength.  The answer is therefore D.
