refraction
refraction when light enters from rarer to denser or vice versa it undergoes bending known as refraction
This is due to the difference in optical density.
That's "diffraction".

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.
The reason for the pole appearing bent when put inside a glass of water is refraction. When a ray of light travels through one medium to the other, it tends to bend or deviate from its original path. Thus a light ray in this case, travels from the air through water, and then again through air and reach the eyes. Thus, the light ray deviates from its original path causing this phenomenon.
the light 'beam' (if you like) will slightly change direction this is bending light, light only travels in straight lines but due to the shape of the glass it changes direction when the beam exits the glass its should go back to its shape of ligh beam .
If you get mirrored tint, it will relflect some of the light but most others filter out light like polarized glasses. The light coming in gets filtered as it hits a grid causing less light to get through.Refraction is bending of light. The window will reflect the light.
If the Glass Block acts as a Prism, then when you shine white light on a it, the White Light refracts into all Primary Colors. When the Light exits the Prism you can see all the rainbow colors.
This is due to the difference in optical density.
Light is affected by the media that it travels through. Even air will bend light. Glass and water certainly bend light.
It is because the glass has more refractive index than air which makes the light bend more through glass than air.
The light will bend as it passes through.
Because glass slab is optically denser than air.
light rays bend away from normal as it passes from denser water to rarer air
The speed of light slows in water.
The speed decreases.

Refraction. White light is a mix of colors in the first place; these colors have different indices of refraction. That is, when moving from air to glass, as in a prism, they will bend at slightly different angles.

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 .
