0.342 x ) photons are required to emit 1 joule of energy.
<h3>What is a photon?</h3>
A photon is a particle of light defined as a discrete bundle (or quantum) of electromagnetic (or light) energy.
We need to find the number of photons emitted per second.
So we have E = hc ÷ λ
= (6.6 x x 3 x m/s) ÷ 6.78 x nm
= 2.92 x Joules
Now number of photons per second = I / E (I = intensity)
= 1 x joule / sec ÷ 2.92 x joule
= 0.342 x
Hence, 0.342 x ) photons are required to emit 1 joule of energy.

Haze is caused by particulate matter from incomplete combustion of car, truck, bus, burning of gasoline and diesel. This could also be caused by the buning of wood, coal, and heating oils from industry, electical generation plants that do not collect some of the pollutants at the smoke stack or exhaust points.
An Element is a pure substance.
