A microwave oven produces electromagnetic radiation with a wavelength of 12.2 cm and a power of 760 W. Calculate the number of microwave photons produced by the oven per second.

The number of microwave photons produced by the oven per second, is 4.665 x 10²⁶ photons / s

Explanation:

Given;

wavelength of the electromagnetic radiation, λ = 12.2 cm = 0.122 m

power of the photon, P = 760 W = 760 J/s

The energy of a single photon of the radiation is given as;

The number of microwave photons produced by the oven per second, is given as;

Therefore, the number of microwave photons produced by the oven per second, is 4.665 x 10²⁶ photons / s

12000j is work done

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
