What is the energy, in eV, of (a) a 450 MHz radio-frequency photon, (b) a visible-light photon with a wavelength of 450 nm, and (c) an x-ray photon with a wavelength of 0.045 nm?

a) Energy is equal to .

b) Energy is equal to 2.76 eV.

c) Energy is equal to 27.6 keV.

See the step by step solution

Step 1. Given Information is :a) a 450 MHz radio-frequency photon b) a visible-light photon with a wavelength of 450 nmc) an x-ray photon with a wavelength of 0.045 nm

We need to find out the energy of the given photons.
