Question

plz tell the formula to find photons energy???​

Answer 1

Answer: The amount of energy in those photons is calculated by this equation, E = hf, where E is the energy of the photon in Joules; h is Planck's constant, which is always 6.63 * 10^-34 Joule seconds; and f is the frequency of the light in hertz

Answer 2

Answer:

Use the folmula

$E = hf \: or \: E = \frac{hc}{wavelength \: }$

Let's Do an example :

Example 1:

Calculate the energy of Photon of radiation whose frequency is 5.00 X 10^14 Hz.

Solution :

$E \: = hf$

h= 6.63 * 10^-34

f= 5.00* 10^14

You get:- 6.63 * 10^-34 • 5.00 * 10^14 = 3.31 * 10^-19 Joule
