diamonds shine brightly because light inside them is reflected repeatedly within its walls.why this repeated reflection increase the brightness of light??

but can you tell me why diamond sparkles more than glass??is it simply because glass absorbs more light?what role does the refractive index of diamond have in this?
Ken G said:klimatos could probably tell us a lot about the clever ways that diamonds are faceted, but it would seem to me that the basic idea behind a "facet" is to have a small region of the diamond emit a lot of light in a given direction, rather than all the diamond emit dimly in all directions. The high index of refraction and high reflectivity allows it to take full advantage of the facet concept.

klimatos said:Passing Point of Information:
Most stones that a jeweler would describe as "glass" are actually rock crystal. This is the crystalline form of silicon dioxide and is not amorphous.
BadBrain said:I honestly didn't know that.
I thought that, in the context of this discussion, "glass" meant "glass".
So sorry!

By the way, what do you think of my rock?
More importantly, what do you think of my analysis of the optical properties of diamonds?
Repeated reflection increases amplitude because each reflection adds energy to the wave. When a wave reflects off of a surface, it bounces back with the same energy it had before, but in the opposite direction. When this happens multiple times, the wave continues to gain energy and its amplitude increases.
Repeated reflection does not affect the wavelength of a wave. The wavelength of a wave is determined by its source and the medium through which it is traveling. Repeated reflection may change the direction of the wave, but it does not impact the wavelength.
No, repeated reflection does not change the frequency of a wave. The frequency of a wave is determined by the source and cannot be altered by reflection. However, if the wave is reflected off of a moving surface, the frequency may appear to change due to the Doppler effect.
The amplitude of a wave may decrease after repeated reflection because some of the wave's energy is lost during each reflection. This can happen if the reflecting surface is not perfectly smooth or if there is friction between the wave and the surface. As the wave loses energy, its amplitude decreases.
There is no limit to how many times a wave can be reflected. However, as the wave continues to reflect, it loses more and more energy, so eventually its amplitude will become too small to detect. This is known as the principle of conservation of energy.
