Change in speed of the light in glass. Fermat showed that time is invariant in light paths.
This results in Light following the Law of Signs.
sin(Air Angle)/speed in air = sin( Glass Angle)/speed in glass .
Glass, water, and other transparent materials can bend light through a process called refraction. This occurs when light passes through different mediums at an angle and changes speed, causing the light to change direction. Mirrors can also bend light through reflection, where the angle of incidence equals the angle of reflection.
This is called refraction. Refraction occurs because light waves change speed when they pass through different mediums, such as air and glass, causing the light to bend.
White light can both reflect and bend. When white light hits a smooth surface, it will reflect off the surface at the same angle it hit it. When white light passes through a different medium like glass, it will bend due to refraction.
The light wave will refract (bend) as it passes from the glass to the air. This is because the speed of light changes when it enters a medium of different optical density, causing the path of the light wave to bend at an angle. The bending occurs due to the change in the velocity of light in the two mediums, causing it to deviate from the normal.
When a ray of light passes through a glass block, it will refract (bend) due to the change in speed as it moves from one medium (air) to another (glass). The light ray will also experience total internal reflection if the angle of incidence is greater than the critical angle, causing the light to reflect back into the glass block rather than refract out of it.
The light will bend into an angle because of the shape of the glass and the location from which the light is coming from.

It all depends on the angle if incidence. In general the light will refract i.e. bend through the glass and come out at the other end. Also, the speed of light will vary through the glass.
Some of the light is reflected off the glass at the same angle - in a manner and angle similar to that of a ball deflected off a surface at a similar angle. This is what happens when light reflects from car windows into our faces. Much of the light, however, will penetrate the glass, so that the light source is seen from the other side. Nevertheless, on contact with the glass, the light that penetrates will be refracted (bent) and travel through the glass at a different angle from that of its original contact with the glass; but once having travelled through the glass, it will leave at its original angle of contact. The amount of refraction depends on a number of factors, but especially, on the thickness of the glass and specific angle of contact involved. So, the light bends as it passes through the glass, but leaves at its original angle.
No, a light ray does not bend if it enters a glass block perpendicularly.

lenses bend light by having the light pass through the glass(or whatever material) of the lense in which the light will slow down. As the light enters the glass the very first part of the ray will slow down alowing other parts to catch up. This makes the light bend towards the normal (perpendicular to side of glass). As the light leaves the glass the oposite occurs. The light that leaves the glass goes faster leaving other parts behind and bending it away form the normal. How much the light bends depends on the shape of the lense the material of the lense and the angle that the light comes in at.
The light ray that enters the drop at the steepest angle will bend the most, due to the phenomenon of refraction. In contrast, the light ray that enters the drop at a shallower angle will bend the least. This is because refraction is greatest when light changes medium at a steeper angle.
Blue light typically has the greatest angle of refraction when passing from air to glass because it has a shorter wavelength compared to red light. This causes blue light to bend more as it enters the glass medium, resulting in a larger angle of refraction.
