Find the color of light whose photon has 4.75x10^-19 j of energy

Explanation:

Energy, E = 4.75 x 10^-19 J

Energy, E = hc/λ

where, λ is the wavelength, h be the Plank's constant and c be the velocity of light.

h = 6.63 x 10^-34 Js

c = 3 x 10^8 m/s

λ = (6.63 x 10^-34 x 3 x 10^8) / (4.75 x 10^-19)

λ = 418.73 nm

So, the colour of light should be violet.
