Answer : The frequency of element is, $6.25\times 10^{14}s^{-1}$

Explanation : Given,

Wavelength of element = $4.8\times 10^{-7}m$

Formula used :

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

where,

$\nu$ = frequency

$\lambda$ = wavelength

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

Now put all the given values in the above formula, we get:

$\nu=\frac{3\times 10^8m/s}{4.8\times 10^{-7}m}$

$\nu=6.25\times 10^{14}s^{-1}$

Therefore, the frequency of element is, $6.25\times 10^{14}s^{-1}$
