Question

Calculate the energy of a photon of electromagnetic radiation whose frequency is 2.94 x 10 to the 14th xbox one

Answer 1

Answer:

$1.95\cdot 10^{-19} J$

Explanation:

The energy of a photon is given by:

$E=hf$

where

$h=6.63\cdot 10^{-34}Js$ is the Planck constant

$f=2.94\cdot 10^{14} Hz$ is the frequency of the photon

Substituting the numbers into the equation, we find:

$E=(6.63\cdot 10^{-34} Js)(2.94\cdot 10^{14} Hz)=1.95\cdot 10^{-19} J$
