7 0

Answer:

frequency of light is 70.47\times 10^{15} \ per\ second

Explanation:

Given

wavelength of light = 4.257\times 10^{-7}\ cm = 4.257\times 10^{-7} \times 10^{-2} \ m= 4.257\times 10^{-9}\ m

Speed of Light = 3\times 10^8 \ m/s

∴ Frequency of Light = \frac{\textrm{Speed of Light}}{\textrm{wavelength}}=\frac{3\times 10^8}{4.257\times 10^{-9}}= 70.47\times 10^{15} \ per\ second
