A light ray is incident on a rectangular glass slab at the angle of 60 what is the angle between the ray coming out of the slap and the normal to the face of a rectangular slab from when it comes out
Answers
Answer: The value of the angle between the ray comping out of a rectangular slab and the normal is 30 degree.
Explanation:
In the given problem, a light ray is incident on a rectangular glass slab at the angle of 60 degree.
The angle of incidence is defined as the angle made by an incident ray with the normal to the surface.
Calculate the angle of incidence.
Angle of incidence= 90 degree - 60 degree
= 30 degree
The angle of emergence is equal to the angle of incidence in a rectangular glass slab.
Angle of emergence = Angle of incidence
= 30 degree
Therefore, the value of the angle between the ray coming out of a rectangular slab and the normal is 30 degree.
Answer:
angle - 30
Explanation:
normal being a straight line we measure it as 90. and incident ray being 60(given).
now to calculate the angle
90-60=30
