Question

What is the energy of a 2.09Hz wave?

Answer 1

This can be solve using the Planck-Einstein Equation

Also known as Planck's Relation, the energy of a photon is given by:

E=hf

, where:

E = Energy (J)

h = Planck's Constant (J*s)= 6.626070040(81)×10−34 Js

f = Frequency (Hz)= 2.09 Hz

E=1.3848*10-33 J
