Angle of incidence ray

Explanation:

The way light reflects off a smooth surface is described by the law of reflection. This law states that the angle of reflection equals the ANGLE OF INCIDENCE RAY.

This is because, when light is reflected off a smooth surface, the light is reflected by all the points that is present on that smooth surface.

Therefore the speed at which the light rays falls on the smooth surface is the same as the speed at which the light ray is reflected back. Due to their speed been the same, the distance of the incidence ray would also be the same as the distance of the reflected ray.

Hence the angle of incidence = angle of reflection.

Answer from: ab847150

Angle of incidence

Explanation:

The angle of reflection is equal to the angle of incidence.

Reflection is defined as the repropagation of light rays incidented on a plane or smooth surface. When a light ray strikes a plane surface we say it is incidented on the surface and all incident light tends to reflect out at the same angle that they strike the surface.

There is a third ray acting on the smooth surface and perpendicular to the surface, this ray is called the normal ray. The angle that the incident ray make with this normal ray is angle of incidence while the angle that the reflected ray makes with the normal ray is the angle of reflection. When light ray strikes the surface, this two angles are always equal according to the second law of reflection.

Glass is transparent to visibile light under normal conditions; however, at extremely high intensities, glass will absorb most of the light incident upon it. this works through a process known as multiphoton absorption. in this process, several photons are absorbed at the same time. if very intense light whose photons carry 2ev of energy is shined onto a material with a band gap of 4ev, that light can be absorbed through two-photon absorption, because two photons have the right amount of energy to bridge the band gap. what is the minimum number of photons of 800-nm light that are needed to equal or exceed the band gap of fused silica glass

Comedians like to joke that the reason we havenâ€™t been visited by intelligent life from elsewhere in the universe is that aliens have been monitoring earthâ€™s broadcasts of intellectually embarrassing tv programs, like gilliganâ€™s island, fear factor, the jersey shore, and the jerry springer showand so consider us far too primitive to merit a visit. letâ€™s check the assertion that aliens could have been receiving them. tv programs are broadcast at a frequency of about 100mhz with about 100kw of total power in 30frames per second, which emanatesroughly uniformly in all directions. assume that interstellar space transmits these broadcasts without attenuation. no matter how smart they are, aliens would require at least one photon per frame to interpret our signals. findthe number of photons per unit time per unit area reaching a receiver on a possible planet in the nearest star system, which is about 4 light-years away (a light-year is the distance light travels in a year). if aliens aimed a receiver or detector directly at earth, how big (in diameter) would it have to be to receive a photon per frame
