Question

The frequency of a wave light is 12*10 raise to 14 s^-1. The wavenumber associated with this light is
A) 5*10^-7 m
B) 4*10^-8 cm^-1
C) 2*10^-7 m^-1
D) 4*10^4 cm^-1​

Answer 1

Answer:

C) 2*10^-7 m^-1

Explanation:

C = wavelength X frequency

3*10^8 = wavelength X 12*10^14

wavelength = 0.25*10^-6

wavelength = 2.5*10^-7
