RE: Science contained in a laser

in StemSocial4 years ago

Hi. Thanks for sharing this. I however have a small comment.

When you say:

In this part of physics, it shows us the importance of photons as an energy source, since it has zero mass and travels in a vacuum with a constant speed, unlike the electromagnetic light waves emitted by the sun, since They are different but both are sources of energy, which served as a basis to continue advancing on this topic of study regarding laser, as the following contribution developed by James P. Gordon and Herbert J. Zeiger built the first maser, which was a device that it worked on the same physical principles as the laser, but it produced a coherent microwave beam.

I am not sure to follow: electromagnetic radiation of the sun also consist in photons and those photons emitted by the sun are not different from any other photon. Their properties (frequency, etc.) could be different of course, but those are still photons.

A representation of the photon and its movement, for visible light the energy carried by a photon is 4x10 ^ -19 July, within this it can manifest eventualities that the amount of movement and its polarization are associated.

What does that mean?
