The frequency of the red light is \(4.62\times 10^{14} s^{-1}\).
Given:
The wavelength of the red light = \(\lambda = 6.50\times 10^{-7}m\)
To find:
The frequency of the red light.
Solution:
The wavelength of the red light = \(\lambda = 6.50\times 10^{-7}m\)
The speed of the light = c = \(3\times 10^8 m/s\)
The frequency of the red light = \(u=?\)
The frequency of red light will be given as:
\(u=\frac{c}{\lambda }\\\\=\frac{ 3\times 10^8 m/s}{6.50\times 10^{-7}m}\\\\=4.62\times 10^{14} s^{-1}\)
The frequency of the red light is \(4.62\times 10^{14} s^{-1}\).
