Question

What is the energy of a photon with a frequency of 5 x 10^14 Hz?

Answer 1

Answer:

$3.315 x 10^-19 J$

Explanation:

Using Eisten's formula, energy is a product of Plank's constant and photon frequency

E=hf

Where f represent frequency, h is Plank's constant and E is energy.

Substituting frequency with 5 x 10^14 Hz and

Planck's constant is 6.63 x 10^-34 J•s.

$E=6.63 x 10^{-34} *5 x 10^{14}=3.315x10^{-19} J$
