Question

calculate wavenumber of radiation having frequency 4 *10^14 Hz

Answer 1

wave number=frequency÷speed of light
wave number=4*10^14÷3*10^8
=1.67*10^6

Answer 2

Answer:=1.33×10^6m-1

Explanation:

wave number =1/wavelength

wave number =frequency/speed

speed of light =3×10^ 8

wave number =4×10 ^14/3×10^8

=1.33×10^6m-1
