Angels are imaginary beings who are mostly based on religious belief. Although sometimes shown as radiant beings, they are not real, and so light cannot pass from them.
When light traveling at an angle passes from one material into another, it undergoes refraction. Refraction is the bending of light as it passes from one medium to another, due to the change in the speed of light. The degree to which the light bends depends on the angle of incidence and the refractive indices of the materials involved.
The speed of light decreases as it passes at an angle from air to water due to the change in the medium's refractive index. This change causes the light waves to bend or refract. The speed of light is slower in water than in air because water has a higher refractive index.
When light passes from air to water, the light is refracted because water is denser than air and therefore slows down the speed of the light.
It moves at a slower speed!
The speed of light is constant and does not change based on the material it passes through. However, when light enters a medium such as glass or water, its speed decreases due to interactions with the atoms in the material.
The speed decreases.
The speed of light in a vacuum is constant and does not depend on external factors like temperature. However, when light passes through a medium other than a vacuum, such as air or water, its speed can be affected by factors like the refractive index of the medium.
Yes, light can bend as it passes through materials with different optical densities, a phenomenon known as refraction. This bending of light occurs due to the change in speed of light as it transitions from one medium to another.
It increases.
When the speed of light in the two media is not the same.
Diffraction.
it travels at c (speed of light in a vacuum)
