Thus the number of photons emitted per second =3.

The energy of each photon is E=hf=hc/λ. Only 3% of the 100 W power is emitted as light, or 3 W= 3 J/s. The number of photons emitted per second equals the light output of 3 J per second divided by the energy of each photon. per second , or almost 1019 photons emitted per second , an enormous number.

Originally Answered: how many 600nm photons must be emitted each second to account for all the light from a 100 watt light bulb? The answer is “none.” There are no photons of exactly 600 nm wavelength.

The number of photons emitted, on the average, by the source per second is: 5 x 10.

h=6.63×10−34Js is Planck’s constant; f=5.00×1014Hz is the frequency.

Example: For a constant frequency, when the velocity of the photon is doubled the wavelength also gets doubled. Thus, the velocity of a photon is dependent on the wavelength.

There is no such thing as an observer traveling with a photon. Photons don’t have experiences.

Light, even though it isn’t charged, behaves like a wave. As a photon moves through space, it exhibits oscillating electric and magnetic fields, and can interact with charged particles. These interactions slow it down, and cause it to move at a speed less than the speed of light as long as they’re in a material.

A photon just looks like a blink of light from a small point. So, when you see a photon (if your eyes are sensitive enough), you see a blip of light. The “size” of a photon is much weirder since photons aren’t “particles” in the traditional macroscopic sense of the word.

Light is a form of energy. Energy can neither be created, nor destroyed. It can only be changed from one form to another form. It is form of energy which can be transformed in another form but cannot be destroyed..
