When light falls perpendicular to an interface of two media, it continues to travel in a straight line without changing direction. There is no change in the speed or wavelength of the light. This phenomenon is known as normal incidence.

What happens when light is perpendicular to glass slab?

When light is perpendicular to a glass slab, it passes through unaffected without any deviation in its path. This phenomenon is known as normal incidence, where the incident light ray and the refracted ray are along the same line.


How does the angle of light bend when it comes out of the water?

When light travels from water to air, it bends away from the normal (a line perpendicular to the water-air interface). This bending of light is known as refraction, and it occurs because light travels at different speeds in different mediums, causing the change in direction.


Why does no refraction occurs when the media have the same index of refraction?

Reflection happens only at the interface between two media, and two media with the same index of refraction act as if they were a single medium. Thus, at the interface between media with the same index of refraction, there is no reflection, and the ray keeps going straight. Continuing this line of thought, it is not surprising that we observe very little reflection at an interface between media with similar indices of refraction.


What happens if the ray of light hits the mirror?

When a ray of light hits a mirror, it is reflected back at an equal angle from the normal (a line perpendicular to the surface of the mirror). This is known as the law of reflection.


What happens to some of the light before entering a glass block?

When light enters a glass block, it undergoes reflection and refraction. However at the glass air interface, refraction occurs to a larger extent than refraction and hence some of the light is reflected while the rest of it enters the glass block.

When was Point Perpendicular Light created?

Point Perpendicular Light was created in 1899.


What are the 2 conditions when the direction does not change on refraction?

-- Light approaches the boundary between any two media along the normal direction. -- Light approaches the boundary at any angle and the indexes of refraction of both media are equal.


What happens when light passes into a material where the speed of light is faster?

-- Its speed increases. -- Its wavelength increases. -- It refracts away from the normal to the interface at the point of incidence.


What happens when light moves from a material in which it's speed is higher to a material in which it's speed is lower?

-- its speed decreases -- its wavelength increases -- if it doesn't approach the boundary perpendicular to it, then it bends closer to the perpendicular

What happens when light rays hits a very smooth surface?

It is reflected at the same angle to the normal. The normal is a line perpendicular to the surface.
