If light rays entered from one medium to another at 90 Degrees of the surface between the mediums, then the light rays would not be retracted. The light will straight through from the first medium to the second.
as usual.... it gets reflected, absorbed or refracted through a particular angle... the angle being dependent on the relative refractive index between the two mediums.
A direct wave is a radio wave that travels directly through space without getting refracted by the ionosphere. In other words, it travels straight to the receiving antenna without being refracted.
It's just after - and it's green sunlight being refracted by the atmosphere to your eye.
If the light truly "bounces back", then it is being reflected. Refraction is the bending of electromagnetic waves like light or radio.
When an object is submerged in water (higher density medium) they seem shallower if you are looking at it from air (lower density medium). This is because the light rays slow down as they move from a medium of lower density (air) to a medium of higher density (water) and tend to refract (bend) towards the normal (surface of the water) hence the seem shallower (closer) than they actually are!

If a beam of light enters a substance with a higher density than air and at an angle, the light is refracted so that an object on the far side of the substance appears to be closer to the observer. If the density of the substance is lower than that of air, the light is refracted away from the observer and the object being viewed appears to be farther away.
Refrangibility is the quality of being, capable of being refracted.
Its being Refracted.
Secret ballot
Rainbows are the result of sunlight being refracted by drops of water in the air.
By refraction. The longer wavelengths(red) refract to a lesser angle than shorter wavelength (blue). See a picture/immage of a white light beam being refracted through a glass prism.
They pee straight down, but they angle their body to make it go backwards from being used to sitting on the toilet and to avoid the feet. Also, they can not bend forward enough to have the same angle.
being a nice and helpful good angle.

The light bends. Depending on whether it is a concave or convex mirror, the light is either being refracted or reflected
