Frequency is the number of times an event occurs. The frequency of the red light is 4.1653 x 10⁻¹⁴ Hz.
Frequency can be defined as the number of times a repeating event occurs.
Given to us
Speed of light, c = 3. 0 × 10⁸ of m/s.
The wavelength of the red light, λ = 6.5 x 10 ⁻⁷ m
We know that frequency of light can be written as,
[tex]f = \dfrac{c}{\lambda}[/tex]
[tex]f = \dfrac{3.0 \times 10^8 }{6.5 \times 10^{-7}}\\\\f = 4.6153 \times 10^{-14}\ Hz[/tex]
Hence, the frequency of the red light is 4.1653 x 10⁻¹⁴ Hz.
