What happens to a ray of light as it enters and leaves a glass block?
The ray of light gets refracted. Depending on the medium it is entering, it will bend either to or away from the normal. For example, if it is entering a glass block from air, it will bend towards the normal, and if it leaves a glass block and enters air it will bend away from the normal. The amount the ray bends depends on the angle of incidences and the refractive indices of the two mediums, and are governed by Snell's Law.
What happens to some of the light before entering a glass block?
When light enters a glass block, it undergoes reflection and refraction. However at the glass air interface, refraction occurs to a larger extent than refraction and hence some of the light is reflected while the rest of it enters the glass block.
What happens to the direction of a light ray as it moves from air into Perspex?
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.
How do you perform an experiment to find the refractive index of a glass block?
To find the refractive index of a glass block for a particular wavelength of light, shine a beam of light of that wavelength through a material for which the refractive index n1 is known onto the glass block such that the angle between the beam and the block's surface θ1 is between zero and 90 degrees. Measure the angle between the part of the beam that enters the block and the block's surface θ2 and use Snell's law:n2 = n1 cos(θ1) / cos(θ2).Note: Typically Snell's law is expressed in terms of the angle between the beam and the direction normal to the interface and there for sines are used instead of cosines, but the use of cosines allowed the question to be answered without assuming knowledge of the concept "normal" to the interface.
What happens when a ray of light enters a glass block at 90 degrees?
It gets bent. (it bends away from the normal. if you put it, say on the right side, it will come out of the left side.

What happens when a ray hits a block at a different angle?
It reflect.Reflecting is the bouncing back of light

What happens when you shine light through a glass cuboid?
This will depend on the angle of incidence. If the light source is perpendicular to the edge of the the block then it will pass through with no change in direction. However if the light source is not perpendicular then the light will alter in direction slightly due to the change in speed of the light waves (light travels slower through the block than the air). When leaving the block the light will resume its original trajectory but slightly offset (parallel to the original beam).
Does a light ray bend if it enters a glass block perpendicularly?
No, a light ray does not bend if it enters a glass block perpendicularly.

What happens when a ray of light is directed at a block of glass?
When a ray of light is directed at a glass block, it may be reflected. However, in most cases, refraction will take place when the ray is redirected in a different angle.
Which angle hits a mirror or glass block?
The angle does not hit anything! A ray of light hits a mirror or glass block and the angle that the ray makes with the vertical at the point of contact is the angle of incidence.

What happens to cooling system when engine is cold?
the water continues to cycle through the water pump, radiator, and heater core until the engine reaches sufficient temperature to open the thermostat. when the thermostat opens, cooler water enters the engine block and heads and warmer water is pulled out of the block, enters the radiator to be cooled, and the cycle continues
