Frequency = speed of light / wavelength
= 3*10^8 / 6.50 * 10^-7
=4.61 * 10^14 sec^-1
The frequency of the red light is [tex]4.62\times 10^{14} s^{-1}[/tex].
Given:
The wavelength of the red light = [tex]\lambda = 6.50\times 10^{-7}m[/tex]
To find:
The frequency of the red light.
Solution:
The wavelength of the red light = [tex]\lambda = 6.50\times 10^{-7}m[/tex]
The speed of the light = c = [tex]3\times 10^8 m/s[/tex]
The frequency of the red light = [tex]\nu=?[/tex]
The frequency of red light will be given as:
[tex]\nu=\frac{c}{\lambda }\\\\=\frac{ 3\times 10^8 m/s}{6.50\times 10^{-7}m}\\\\=4.62\times 10^{14} s^{-1}[/tex]
The frequency of the red light is [tex]4.62\times 10^{14} s^{-1}[/tex].
