(a)![2.5\cdot 10^{-6}eV](/tpl/images/0431/1113/5f06a.png)
The energy of a photon is given by:
where
For the microwave photon,
So the energy is
And converting into electronvolts,
(b)![2.5 eV](/tpl/images/0431/1113/11fad.png)
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)![2500 eV](/tpl/images/0431/1113/f854c.png)
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,
