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.

The incident ray is the ray of light that first strikes the surface of a medium or interface, while the emergent ray is the ray of light that exits the medium after being refracted or reflected. The direction of the emergent ray depends on the angle of incidence and the properties of the medium.
The angle between the incident ray and the normal is called the angle of incidence.
The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.
It is called the angle of incidence! Hope this helped! thank u it did
The angle of incidence is defined as the angle between the incoming light and the line that is normal to the surface at the point where the light 'hits' the surface. The reflectrion angle is the same as the incidence angle. If the angle between the incident ray and the mirror ray is 50, then the angle of incidence is half of this. That is, 25 degrees.
The angle Between the path of incident ray and emergent ray
The incident ray is the ray of light that first strikes the surface of a medium or interface, while the emergent ray is the ray of light that exits the medium after being refracted or reflected. The direction of the emergent ray depends on the angle of incidence and the properties of the medium.
Angle of emergence is the angle which the normal makes with the emergent ray.
The angle between the incident ray and the normal is called the angle of incidence.
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.
The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.

The relationship between the incident angle and the reflected angle in light reflection is described by the law of reflection. This law states that the angle at which light hits a surface (incident angle) is equal to the angle at which it bounces off that surface (reflected angle).
incident ray and the normal to the surface at the point of incidence.
The angle between the incident ray and the normal is called the angle of incidence because it represents the angle at which the light ray strikes the surface. It is important in understanding how light behaves when it interacts with a surface, such as reflection or refraction.
The angle of emergence is the angle between the emergent ray and the normal to the interface when light or a wave passes from one medium to another. It is important in understanding how light or waves change direction when they pass through different mediums.
