Anitrogen laser pulse with a wavelength of 337 nm contains 3.83 mj of energy. how many photons does it contain?

number of photon will be equal to

Explanation:

We have given wavelength of nitrogen laser pulse is 337 nm

So wavelength

Velocity of light

Plank's constant

So energy of each photon

Total energy is given = 3.38 mJ = 0.00338 J

So number of photon will be equal to

So number of photon will be equal to

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
