Answer:
photons are emitted per second in a
Watt microwave oven.
Step-by-step explanation:
The expression for the power is:-

Also,

Where,
n = the number of photons
h = Plank's constant having value

c = the speed of light having value

= the wavelength of the light
So,

Thus, the expression for photons per second is:-

Given that:-
Power = 10³ Watt
( 1 cm = 0.01 m)

So,

photons are emitted per second in a
Watt microwave oven.
