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 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.
When a ray of light enters a glass block at 90 degrees, it continues in a straight line without bending. This is because there is no change in the speed of light when it enters the glass block at a perpendicular angle.
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.
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.
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.

The light ray changes direction as it enters the glass block due to refraction, where the speed of light changes as it passes from one medium to another. This change in direction is caused by the bending of the light ray towards the normal of the surface at the point of entry.
No, a light ray does not bend if it enters a glass block perpendicularly.
When light passes through a glass block, it undergoes refraction, which is the bending of light as it enters the glass and again as it exits. The speed of light changes as it moves from air to glass, causing the light rays to change direction.
When light enters a glass block, it slows down and bends (refracts) due to the change in medium density. As the light passes through the block, it continues to bend until it reaches the other side, where it exits the block and resumes its original speed and direction.
Pupils "constrict" when light enters, and "dilate "when the lighting dims
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.
