Question

the frequency of a wave is is 6 x 10 ^ 15 second inverse what is its wave number​

Answer 1

Given:

Frequency of a given wave = 6 × 10¹⁵ s⁻¹

To find:

Wave number of a given

Solution:

Frequency is defined as the number of oscillations in an given interval of time.

Wave number of a wave is defined as the frequency of given wave in space.

Relationship formula between frequency and wave number is given as-

                  $\bar{\nu } = \frac{1}{\nu }$

here, $\bar{\nu }$ = wave number of a wave

         $\nu$ = frequency of a wave

putting values of $\nu$ in the above equation we get,

             $\bar{\nu} = \frac{1}{6 \times 10^1^5} s$

             $\bar{\nu} = \frac{1}{6} \times 10^-^1^5 s$

             $\bar{\nu} = 0.17 \times 10^-^1^5 s$

Therefore, wave number of given wave is 0.17 × 10⁻¹⁵ s.
