Question

physics homework helpCell phones use electromagnetic radiation with an energy of about 1.08J/mol photons. Calculate the wavelength and frequency that can be used to describe light with this energy.

Answer 1

The formula for calculating the energy of radiation is expressed as

E = hf

where

E is the energy

h is the planck constant = 6.626 x 10^-34

f is the frequency of the wave

From the information given,
