it bends
what happens is the light is refracted or bent to the normal as in the other surface the line is refracted away from the normal refracted light coming out of the perspex block is parallel to the incident light refraction is caused as the light hits the block from a different angle lets say 25 degrees the particles are normally all lined up and go the same speed but as it hots the block from a different angle one particle will hit first the block and then the next and so on making each particle separate causing it to bend.
That's related to the fact that the speed of light in glass is slower than the speed of light in air.
The refraction of light is the change in direction of a light ray when it crosses a boundary between two transparent substances. Refraction of light is the change in direction of a light ray due to a change in its speed as it goes from one medium to another.The speed and wavelength of a light ray change when this occurs, but the frequency remains the same.When light travels from denser medium to rarer medium it moves away from the normal [line at right angles to the boundary] and when light travels from rarer to denser it moves towards the normal.
Nothing special. But when light travels from one medium to another (from air to water for example) it is refracted. One answerer said a rainbow. A rainbow is caused by the different wavelengths (colors) of light are refracted at slightly different angles, so that we see different colors appearing at different positions.

Light is perfectly reflected from a surface when the roughness of the surface is small compared to the wavelength of the light. Otherwise the reflection is diffuse.Light is refracted when it passes from one medium to another of a different refractive index. One in which the light travels at a different speed than in vacuo.

Refraction occurs when light passes from one medium to another. If you have your feet in a pool your legs looked bent because the light is being refracted as it moves from under the water through the air on its way to your eye.
startle reflex
The speed of the ray is slower in the denser material. the denser material encounters more interference (time) to travel the same distance.
