Question

The green light has a wavelength of 535 nm. Calculate the energy of a photon of green light.

Answer 1

Explanation:

wavelength is given hence energy is easy to ginf

Answer 2

The energy of a photon can be calculated using the formula:

E = h * v

where E is the energy of the photon, h is the Planck constant (6.62607015 x 10^-34 J.s), and v is the frequency of the light wave. The frequency of light can be calculated from its wavelength using the formula:

v = c / λ

where c is the speed of light (299,792,458 m/s) and λ is the wavelength of the light.

Substituting the values for h, c, and λ, we get:

E = (6.62607015 x 10^-34 J.s) * (299,792,458 m/s) / (535 x 10^-9 m)

E = 3.98 x 10^-19 J/photon

So, the energy of a photon of green light with a wavelength of 535 nm is approximately 3.98 x 10^-19 J/photon.
