Refraction through a glass prism

In an experiment on tracing the path of the rays of light passing through a glass prism, the correct setting of protractor (D) for measuring the angle of incidence ∠i in diagram is

• i

• ii

• iii

• iv

A student showed the following traces of the path of a ray of light passing through a glass prism:

• i

• ii

• iii

• iv

Four students A, B, C and D perform experiment on tracing the path of light ray through a glass prism. The correct position of the pins used to describe incident ray is shown on paper by four of them, respectively as shown above. The correct result is obtained by

• A and B both

• B and C both

• A and D both

• A only

For the refraction of a ray of light through a glass prism, the path of a ray of light is shown above. The angle of incidence, the angle of emergence and the angle of deviation respectively have been represented by

• Y, N, Z

• X, Z, M

• X, N, Z

• X, M, Z

In an experiment to trace the path of a ray of light through a glass prism for different values of angle of incidence, a student would find that the emergent ray

• is parallel to the incident ray.

• perpendicular to the incident ray.

• is parallel to the refracted ray.

• bend at an angle to the direction of incident ray.

Sumitra was given two glass prisms. One was made of ordinary glass and other one was of flint glass (Given that refractive index of flint glass is more than that of ordinary glass). She traced the path of rays through both and after observing the diagram and concluded that bending of light for the given angle of incidence was

• more in the prism made of flint glass.

• more in the prism made of ordinary glass.

• same in both the glass prisms

• independent of the nature of glass of which the prism was made

While performing experiment to trace the ray of light through a triangular glass prism, a student is asked to draw the boundary of a prism on a paper. This is done to

• see whether the given prism is triangular or not.

• ensure that the prism is always kept within the boundary during experiment.

• check whether the edges of the prism are broken or not.

• make the diagram more clear.

Which of the following is the best set-up for tracing the path of ray of light through a glass prism?

• (i) only

• (ii) only

• (iii) only

• (iv) only
