A heat lamp produces 32.8 watts of power at a wavelength of 6.5 μm. How many photons are emitted per second?

Explanation:

The expression for the power is:-

Also,

Where,  

n is the number of photons

h is Plank's constant having value

c is the speed of light having value

is the wavelength of the light

So,  

Thus, the expression for photons per second is:-

Given that:-

Power = 32.8 Watt

So,  

we can see how the government has failed them.
