Answer : The frequency of element is,
6.25* 10^(14)s^(-1)

Explanation : Given,

Wavelength of element =
4.8* 10^(-7)m

Formula used :

$\\u=(c)/(\lambda)$

where,

$\\u$ = frequency

$\lambda$ = wavelength

c = speed of light =
3* 10^8m/s

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

$\\u=(3* 10^8m/s)/(4.8* 10^(-7)m)$

$\\u=6.25* 10^(14)s^(-1)$

Therefore, the frequency of element is,
6.25* 10^(14)s^(-1)
