Light – Reflection and Refraction Class 10 MCQ Quiz – Test Your Understanding!

In the below diagram light is traveling through different media. It is noted by a scientist that ∠1 = ∠3 = ∠4 but ∠2 = ∠1. Which of the following statement would be correct?

A. Noor, a young student, was trying to demonstrate some properties of light in her science project work. She kept ‘X’ inside the box (as shown in the figure) and with the help of a laser pointer made light rays pass through the holes on one side of the box. She had a small butter paper screen to see the spots of light being cast as they emerged.

If the object inside the box was made of a material with a refractive index less than 1.5 then the

Examine the below figure and state which of the following options is correct.

(one small box in the figure is equal to 1 cm)

As a ray of light entered medium P from medium Q, its velocity increased.

What can be said about the refractive index of medium P as compared to that of medium Q?

While looking at the below diagram, Nalini concluded the following:

1. The image of the object will be a virtual one.
2. The reflected ray will travel along the same path as the incident ray but in the opposite direction.
3. The image of the object will be inverted.
4. This is a concave mirror and hence the focal length will be negative.

Which one of the above statements is correct?

In the diagram shown below, a beam of light is traveling from inside a glass slab to air. Which of the marked paths will the ray of light take as it emerges from the glass slab?

Which of the following mirror is used by a dentist to examine a small cavity in a patient’s teeth?

A. Noor, a young student, was trying to demonstrate some properties of light in her science project work. She kept ‘X’ inside the box (as shown in the figure) and with the help of a laser pointer made light rays pass through the holes on one side of the box. She had a small butter paper screen to see the spots of light being cast as they emerged.

What could be the ‘X’ that she placed inside the box to make the rays behave as shown?
