Explanation:
It is given that wavelength of light is 310 nm or \(310 \times 10^{-9}\) m. Relation between wavelength, speed of light and frequency is as follows.
\(u = \frac{c}{\lambda}\)
where, \(u\) = frequency
c = speed of light = \(3 \times 10^{8}\) m/s
\(\lambda\) = wavelength
Hence, putting the given values into the above formula as follows.
\(u = \frac{c}{\lambda}\)
\(u = \frac{3 \times 10^{8} m/s}{310 \times 10^{-9} m}\)
= \(9.67 \times 10^{14}\) per second
Thus, we can conclude that the frequency of given light is \(9.67 \times 10^{14}\) per second.
