When light enters a glass block, it changes speed and bends due to refraction, causing the light beam to deviate from its original path. The light exits the glass block at a different angle than it entered. This phenomenon is a result of the change in the speed of light as it passes from air into the denser medium of the glass.
When light is shined at a glass block, some of the light is transmitted through the block, some is reflected, and some is absorbed. The transmitted light changes its direction due to refraction as it passes through the glass block.
When you shine light through a glass block, it is called refraction. Refraction is the bending of light as it passes from one medium, such as air, into another medium with a different optical density, such as glass.
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.
Light can shine through transparent substances like glass, water, and air. These materials allow light to pass through them without significant obstruction.
If the two panes of glass are placed perpendicular to each other, the light passing through them will mix, and the screen will be illuminated with a combination of red and green light, creating a yellow color where the two beams overlap.

It goes out the other side.
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).
A transparent/translucent medium with a density that is different to the one it has just left is necessary to diffract light. For example, you could shine light into a block of glass to diffract it at a different angle to when it entered.
Unless it`s colored glass, it will still shine its original color.
