R P Goyal and S P Tripathi Solutions for Chapter: Refraction Through a Lens, Exercise 1: EXERCISE-5(A)

The diagram below shows a lens as a combination of a glass block and two prisms.

Complete the path of the incident ray $AB$ after passing through the lens.

The diagram below shows a lens as a combination of a glass block and two prisms.

The final emergent ray either meets $X{X}^{\text{'}}$ at a point or appears to come from a point on $X{X}^{\text{'}}$. Label it as $F$. What is this point called?

In the below figure, $F_1$ and $F_2$ are the positions of the two foci of the thin lens. Draw accurately the path taken by the light ray $AB$ after it emerges from the lens.

In the below figure, $F_1$ and $F_2$ are the positions of the two foci of the thin lens. Draw accurately the path taken by the light ray $AB$ after it emerges from the lens.

In the figure below, $F_1$ and $F_2$ are the two foci of the thin lens and $AB$ is the incident ray. Complete the diagram to show the path of the ray $AB$ after refraction through the lens.

In the figure below, $F_1$ and $F_2$ are the two foci of thin lens and $AB$ is the incident ray. Complete the diagram to show the path of the ray $AB$ after refraction through the lens.

A ray of light after refraction through a lens emerges parallel to the principal axis of the lens. The incident ray either passes through or appears to meet at:

A ray of light incident on a lens parallel to its principal axis, after refraction passes through or appears to come from:
