Answer:

Given : Frequency of the electromagnetic wave = 31015 Hz .

To find : Wave number

Definition: Wave number is defined as the number of waves in a unit length. In simple words, it is the reciprocal of Wavelength.

Formula : wave number = 1/wavelength.

Calculation:

wavelength = (velocity of light)/freq.

= (3*10^8 )/31015

= 9.67 *10^3

= 9670 metres.

Wavenumber = 1/9670

= 0.00010341

Answer is 0.00010341
