Explanation:
The energy of a photon is given by :
[tex]E=\dfrac{hc}{\lambda}[/tex]
Where
h is Planck's constant
c is the speed of light
[tex]\lambda[/tex] is wavelength
or
[tex]E=hf[/tex], f is the frequency
Energy is directly proportional to the frequency of an object.
The energy transported by a wave is directly proportional to the square of the amplitude.
