Wavelength changes from short to long B. Frequency changes from low to high C. Speed of light changes from slower to faster D. Wavelength changes from long to short E. Frequency changes from high to low F. Speed of light changes from faster to slower G. Wavelength and frequency change but speed of light remain constant For our human eyes, as color of the visible light changes from Red to Violet, which of the following statement(s) is (are) true?

Explanation / Answer
All the transverse electromagnetic waves in vacuum have the same speed v ~ 3×108m/s. It's frequency and wavelength changes .
Red light has a longer wavelength and lower frequency.
Violet light has a shorter wavelength and higher frequency.
The true statements are :
B. Frequency changes from low to high.
D. Wavelength changes from long to short.
G. Wavelength and frequency change but speed of light remain constant.
