The incident ray and the emergent ray will always be?
The Incident ray, falling on the glass slab, and the Emergent ray will always be parallel to each other.
Why incident ray and emergent ray are parallel to each other in the refraction of light?
Because both incident ray and emergent ray have same slope.
What is emergent ray in refraction of light?
The emergent ray is the ray of light which passes through a denser medium(glass) to a rarer medium(air).
What is emergent angle?
Angle of emergence is the angle which the normal makes with the emergent ray.
Give simple detail of angle of deviation?
The angle Between the path of incident ray and emergent ray
Why emergent parallel incident ray in a glass slab?
This is because the amount of refraction taking place at the parallel faces of a glass slab is equal but opposite and since the faces are parallel the emergent ray emerges parallel to the incident ray with lateral displacement.
What is angle of emergence?
Angle of emergence is the angle which the normal makes with the emergent ray.
Is there a relationship between lateral displacement and the emergent ray?
the thickness of the glass block
State two factors on which the lateral displacement of emergent ray depend?
temperature , thickness
What is a glass slab?
it is a substance made of glass having 3 dimensions and is cuboid shaped. It does not deviate the light. This means that the incident and the emergent ray are parallel. The slab only produces lateral (sideways) shift or displacement.
What is the definition of angle of minimum deviation for prism?
the smallest angle between the incident and the emergent ray
Is point Reyes submergent or emergent?
emergent
