Question

if all the energy from a 93 W light bulb ?is emmited on average at 530.0 nm, how many 530.0 nm photons must be emitted each second to account for all 93w

Expert Solution
Step 1

Given Data:-

Power of the bulb is P=93 W

Wavelength of each photon is 

λ=530.0 nm

 =530 nm×10-9 m1 nm

 =530×10-9 m

 

Required:-

We need to calculate the number of photons emitted per second on account of 93 W.

 

Formula:-

Energy of a photon having frequency ν is 

E=hν         h is the Planck's constant.

=hcλ     λ is the wavelength of the photon and c is the speed of light in free space.
