When a beam of light meets a perspex surface at an angle, it will undergo refraction, which is the bending of light as it passes from one medium to another with a different refractive index. The angle of refraction will depend on the angle of incidence and the refractive indices of the two materials.

What happens when the light goes through the perspex?
When light goes through Perspex, which is a type of transparent plastic, it continues in a straight line unless it refracts (bends) due to the different medium it is passing through. The light may also undergo total internal reflection or scatter within the Perspex material. Ultimately, the Perspex allows light to pass through with minimal distortion.
How does perspex transmit light?
Perspex, also known as acrylic, transmits light due to its transparent chemical structure. When light strikes perspex, it passes through the material rather than being absorbed or reflected. This is because perspex has a high level of light transmission and optical clarity compared to other materials.
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.
What happens when a ray of light enters a perspex block?
When a ray of light enters a perspex block, it undergoes refraction, bending towards the normal due to the change in speed as it enters the denser medium. The angle of refraction is determined by Snell's Law, which relates the angles of incidence and refraction to the refractive indices of the two mediums.
What are the angel of reflection and the angle of incidence?
The angel of reflection refers to the angle at which light is reflected off a surface, equal to the angle of incidence where the light strikes the surface. The angle of incidence is measured between the incident light ray and the normal (perpendicular line) to the surface at the point of incidence.

Is perspex transparent?
Yes, Perspex (also known as acrylic) is transparent. It is a clear material that allows light to pass through it, similar to glass.
What is the critical angle of perspex and water?
The critical angle for perspex and water is approximately 41 degrees. This means that any light ray entering perspex from water at an angle greater than 41 degrees will be totally internally reflected within the perspex.
What is the known value of the indices of refraction for perspex block?
The index of refraction for perspex, also known as acrylic or PMMA, is approximately 1.49. This means that light travels about 1.49 times slower in perspex than in a vacuum. The exact value may vary slightly depending on the wavelength of light.
What happens when light hits a rough surface?
when light hits a rough surface it scattters.
Perspex has a higher refractive index than air Light entering air from perspex will?
bend towards the normal as it enters air from perspex due to the change in refractive indices. This is known as refraction and occurs whenever light passes from one medium to another with a different refractive index.
What happens when hits a black surface?
im assuming that u meant "what happens when LIGHT hits a black surface?" the reason for this is that the black surface ABSORBS the light, and so none of the light waves can be reflected back (which is what makes it look black)
Are you a Light Angel or a Dark Angel?
Light Angel
