A particular wavelength of red light is 1.5 times a particular wavelength of blue light. What is the ...?

Question

relationship between the frequencies of these two waves?
a) v red = (1.5) (v blue)
b) " " " = (1.2) (v blue)
c) " " " = (0.75) (v blue)
d) " " " = (0.67) (v blue)

Answer 1

if the wave length l1 =1.5l2

the frquency of l1 =1/1.5that of l2

So d is correct the frequency of the red is 0.67 that of blue
