= 4000J
V = √(4000 ÷ 250) = 4 m/s
The wavelength of the emitted photon is(
)= 690nm
<h3>How can we calculate the wavelength of the emitted photon?</h3>
To calculate the wavelength of the photon we are using the formula,

Or,
We are given here,
= The energy difference between the two levels = 1. 8 ev=
C.
h= Planck constant =
Js.
c= speed of light =
m/s.
We have to find the wavelength of the emitted photon =
m.
Therefore, we substitute the known parameters in the above equation, we can find that,

Or,
Or,
m
Or,
=690 nm.
From the above calculation we can conclude that the wavelength of the emitted photon is 690nm.
