Calculate the energy of a photon having a wavelength in thefollowing ranges.(a) microwave, with λ = 50.00 cmev(b) visible, with λ = 500 nmev(c) x-ray, with λ = 0.50 nmev

(a)

The energy of a photon is given by:

where

is the Planck constant

is the speed of light

is the wavelength

For the microwave photon,

So the energy is

And converting into electronvolts,

(b)

For the energy of the photon, we can use the same formula:

For the visible light photon,

So the energy is

And converting into electronvolts,

(c)

For the energy of the photon, we can use the same formula:

For the x-ray photon,

So the energy is

And converting into electronvolts,
