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 to the direction of a light ray as it moves from air into Perspex?
The light ray will bend towards the normal (perpendicular line) when it moves from air into Perspex due to the change in the speed of light between the two mediums. This bending of light is known as refraction.
What happens when a ray of light enters a glass block at 90 degrees?
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.
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 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 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.

When a light ray enters a glass block at an angle what happens to its direction?
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.
Does a light ray bend if it enters a glass block perpendicularly?
No, a light ray does not bend when it enters a glass block perpendicularly. It will continue in a straight path without changing direction when entering the glass block at a 90-degree angle.
What happens when light passes through a glass block?
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.
What happens when the light goes into and comes out of a glass block?
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.
What happens when you shine a light in to a glass block?
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.
What happens to both pupils when light enters?
Pupils "constrict" when light enters, and "dilate "when the lighting dims
