Question

Frequency of a wave is 6*10^15 . Its wave number is

Answer 1

Answer:

v = 1.67 × 10⁻¹⁶

Explanation:

Well , first we should know that what is wave number .

Wave number is nothing but inverse of frequency .

Mathematically ,

v = 1 / f .

where v = wave number

f = frequency

Now we have given Frequency ( f ) = 6 × 10¹⁵ Hz .

Put the value in formula we get

v = 1 / 6 × 10¹⁵

v = 0.167 × 10⁻¹⁵

v = 1.67 × 10⁻¹⁶

Thus we wave number of Frequency  6 × 10¹⁵ Hz  is v = 1.67 × 10⁻¹⁶ .

Some important relation with Frequency are :

Frequency is inverse of time .

i.e . f = 1 / T

Another formula term we have

f = c / λ

where c is velocity of light .

λ is wave length .
