Question

The frequency of a wave is 3*10power 15 sec inverse.its wave number would be

Answer 1

Answer:

Explanation:

See the image for explanation.

I have to write it as they are asking for an explanation

Answer 2

Answer:

10 to the power 7

Explanation:

Because frequency=c/wavelength

(c=speed of light)

=>wavelength=c/frequency

=>wavelength=3*10^8/3*10^15

=10^-7

wavenumber=1/wavelength

1/10^-7=10^7

10 to the power 7 meter inverse
