Neon discharge tubes emit a light with a wavelength of 600. nm that appears deep orange to the human eye. how many photons of this electromagnetic radiation amount to 250. j of energy?

Explanation:

First of all, we need to calculate the energy of one photon with wavelength 600 nm. The energy of each photon is given by

where

is the Planck's constant

is the speed of light

is the wavelength of the light

Substituting numbers into the formula, we find

Now to find the number of photons, we simply divide the total energy (250 J) by the energy of one photon:

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

the body's situation won't change the forces are equal opposit and on the same body
