The angle between the incident ray and emergent ray is called the angle of - Deviation
It depends on the refractive index of the glass slab, the material the light is traveling through before hitting the slab as well as the angle it hits the slab at.
Snell's law:
The refractive index of the medium the light is traveling out of - times - sin for the angle between the ray of light and the normal of the surface = the refractive index of the medium the light is traveling into - times - sin for the angle between the ray of light and the normal of the surface on the other side.
n1 * sin(angle1) = n2 * sin(angle2)
Where:
n1 = Refractive index of the material the light is exiting.
sin(angle1) = Sin for the angle at which the light hits the surface of the glass slab. This angle is measured by drawing a line from the point on the glass slab that the light hits the surface perpendicular to the surface, that is to say at a 90 degree angle against the surface. You then measure the angle between this new line and the line of the ray of light.
n2 = Refractive index of the material the light is entering
sin(angle2) = Sin for the angle at which the light leaves the edge of the glass slab.

∙ 9y agoIt is the angle at which the incoming light beam strikes the mirror. 'Normal' means 'perpendicular', and the 'angle of incidence' is defined as the angle with respect to the normal. These two facts can serve as powerful clues.

What is the definition of angle of minimum deviation for prism?
the smallest angle between the incident and the emergent ray
The angle of incidence is the angle between the incident ray and the?
The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.
What is angle of incident?
It is the angle between an incident ray and the perpendicular to the surface at the point of incidence.
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
The angle of incidence is the angle between the?
The incident ray and the normal .
Give simple detail of angle of deviation?
The angle Between the path of incident ray and emergent ray
What is the definition of angle of minimum deviation for prism?
the smallest angle between the incident and the emergent ray
The angle of incidence is the angle between the incident ray and the?
The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.
What is emergent angle?
Angle of emergence is the angle which the normal makes with the emergent ray.
Why is the constant deviation spectrometer named so?
It is named after the type of prism used in the instrument. A constant deviation prism has the property that the angle between light entering the prism (the incident light) and light exiting the prism (the emergent light) is always the same, no matter what the angle of the incident light to the prism.
What is angle of incident?
It is the angle between an incident ray and the perpendicular to the surface at the point of incidence.
