What is the wavelength of radiation that has a frequency of 7.2×10^11 s−1 ?

Airida [17]

Explanation:

It is known that relation between wavelength and frequency is as follows.

$\lambda = \frac{c}{\nu}$

where, $\lambda$ = wavelength

c = speed of light = $3 \times 10^{8} m/s$

[/tex]\nu[/tex] = frequency

It is given that frequency is $7.2 \times 10^{11} s^{-1}$ . Hence, putting this value into the above formula and calculate the wavelength as follows.

$\lambda = \frac{c}{\nu}$

$\lambda = \frac{3 \times 10^{8} m/s}{7.2 \times 10^{11} s^{-1}}$

= $0.416 \times 10^{-3} m$

or, = $4.16 \times 10^{-4} m$

Thus, we can conclude that wavelength of given radiation is $4.16 \times 10^{-4} m$ .
