A microwave operates at 7.42 mm wavelength. How much energy is produced in Joules from 359 photons?
alisha [4.7K]

Answer:

E=9.62\times 10^{-21}\ J

Explanation:

Given that,

The wavelength of a microwave is 7.42 mm or 0.00742 m

No. of photons, n = 359

We need to find the energy produced by this no of photons. It can be given by the formula as follows :

E=\dfrac{nhc}{\lambda}\\\\E=\dfrac{359\times 6.63\times 10^{-34}\times 3\times 10^8}{0.00742}\\\\=9.62\times 10^{-21}\ J

or

E=9.62e^{-21}\ J

So, the required energy is 9.62\times 10^{-21}\ J.
