QUESTION:
List the types of electromagnetic radiation in order of increasing energy per photon.
(a) radio waves
(b) microwaves
(c) infrared
(d) ultraviolet
ANSWER:
Solution 33P
Step 1:
The photon energy is the energy carried by a single photon with a certain electromagnetic wavelength and frequency. The higher the photon's frequency, the higher its energy. Equally, the longer the photon's wavelength, the lower its energy.
It is calculated using the formula :
E = or E = hf
Where, E = energy per photon
h = planck’s constant = 6.626 10-34 J /s
c = speed of light = 3108 m /s
= wavelength of light
f = frequency of light.
