If the wavelength of a beam of light were to double, how would that affect its frequency?
A) The frequency would be four times higher.
B) The frequency would be two times higher.
C) The frequency would be two times lower.
D) The frequency would be four times lower.
E) There is no relationship between wavelength and frequency.
