Question

Calculate the energy of a photon of light with
a frequency of 5.109 × 1016 Hz.

Answer 1

The energy of the photon is 1.718×10−26J.

Step-by-step explanation:

The energy of the photon is

1.718 × 10 − 26J. You use the formula E =
`(hc)/(λ)`, where h is Planck's Constant,c is the speed of light, and λ is the wavelength of the photon.

E=
`(hc)/(λ)`=
`(6.626×10−34J⋅ s×2.998×108m⋅s-1)/(11.56m)` = 1.718×10−26J.
