What is refraction ray?
A refracted ray passes through the medium, at a different angle to the normal than the incident ray. by Ronan Lavery
How to derive lateral shifting formula?
When a ray of light from a medium is incident on another medium with different optical density, the ray bends due to refraction. The perpendicular distance between the emergent ray and the incident ray is called the lateral shift. The angle which the incident ray makes with the normal is called angle of incidence denoted by 'i' and the angle made by the refracted ray with the normal is called the angle of refraction denoted by 'r'. Lateral shift is given by the formula:- Where t is the thickness of the glass slab, i is the angle of incidence and r is the angle of refraction
What is angle of incident?
It is the angle between an incident ray and the perpendicular to the surface at the point of incidence.
When the refracted light is bent back into the incident material is called a?
total internal refraction
When light is traveling along the normal will its direction change?
This is total internal reflection where the angle of refraction is 90 degrees and its incident angle would be the critical angle(angle of incident for which the angle of refraction is 90).... This hapens when the angle of incidence is in a medium more dense than the angle of refraction's medium
Would you be able to observe the refraction of light if the incident light were perpendicular to the medium?
No, you wouldn't be able to.
When light is incident on a boundary between two mediums it often slows down or speeds up. when it does this the path the light travels can change. this is called?
refraction
What does refraction rely on?
It relies on a change of the speed of light in certain materials.
The bending of light as it passes into a transparent material of different optical intensity is known as?
Refraction: light speeding up and slowing down, between mediums. When light travels from a more dense material to a low density material like glass to air, light will be refracted away from the normal. When light travels from a less dense material to high density material, for example from air to water, light will be refracted towards the normal. Similarly, the refracted ray is a ray that shows the direction that light travels after it has crossed over the boundary. In the diagram, a normal line is drawn to the surface at the point of incidence. This line is always drawn perpendicular to the boundary. The angle that the incident ray makes with the normal line is referred to as the angle of incidence. Similarly, the angle that the refracted ray makes with the normal line is referred to as the angle of refraction. The angle of incidence and angle of refraction are denoted by the following symbols: = angle of incidence = angle of refraction --- = Normal 90'
What is phase change in light of wavelength 600-NM incident in a material with index of refraction n equals 1.38 when it reflects from a material with index of refraction n equals 1.40?
When a light ray is incident on a boundary of greater density than the current medium, the reflected ray undergoes a 180 degree phase change
When light is incident on a surface at 30 degrees it is found that reflected ray and refracted ray are perpendicular to each other Find angle of refraction How?
The angle of incidence equals the angle of reflection.
What is refraction ray?
A refracted ray passes through the medium, at a different angle to the normal than the incident ray. by Ronan Lavery
Why there is no refraction of light when light falls perpendicular to the boundary separating two media of different refractive index?
Take a look at the formula for refraction, and see what angle you get. n1 sin θ1= n2 sinθ2 Another way to look at it is simply "for symmetry reasons". If the incident ray of light were to be refracted in any other direction, why would one direction be preferred to another one? - In this case there is no "reference plane" to specify the direction.

What are the similarities of reflection and refraction?
REFLECTION: IF a light ray in incident on a surface if it bring back to same medium is called reflection REFRACTION: IF a light ray in incident on a surface and going to another medium is called reflection and there is a a law for refraction that is SNELL'S LAW
What is angle of incident?
It is the angle between an incident ray and the perpendicular to the surface at the point of incidence.
What happens to a beam of light once it hits water?
The incident ray (the incoming light) hits the water and then the speed is slowed. It is called 'Refraction'. Which is the bending of light through a translucent or transparent object.
