(a) Write the approximate wavelength for (i) blue, and (ii) red light
(b) The wavelength of violet and red light are 4000Å and 8000Å respectively. Which of the two has higher frequency?

Text Solution

Verified by Experts

We know that,
`c=lamdav`
or `v=c/lamda`
`thereforevprop1/lamda` (As c is always constant)
Hence, lower wavelength i.e., 4000 Å has higher frequency.
