1. The change in the direction of a wave passing from one medium to another is termed as —————.

1. Interference
2. Mirage
3. Diffraction
4. Refraction

Explanation: When the direction of the wave is changed, it is termed as refraction.

2. What would be the angle of incidence for a light ray having zero reflection angle?

1. 180 degrees
2. 90 degrees
3. 0 degree
4. 45 degrees

Explanation: Since we know ∠i = ∠r for reflecting surfaces, therefore if the angle of reflection is zero, then the angle of incidence will also be zero.

3. Light can be focused on our retina through which of the following phenomena?

1. Interference
2. Refraction
3. Diffraction
4. Mirage

Explanation: Light rays are focused on the retina after getting refracted through the eye lens.

4. Speed of light in a vacuum is represented as —————.

1. a
2. v
3. c
4. l

Explanation: The symbol to represent the speed of light in a vacuum is c.

5. A full length of the image of a distant tall building can be seen using —————.

1. a convex mirror
2. a plane mirror
3. a concave mirror
4. none of the options

Explanation: A convex mirror always forms a virtual and smaller image irrespective of the position of the object. So, a full-length image of a distant tall building can definitely be seen by using a convex mirror.

6. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant. It is given by ……………………

2. Snell’s law
3. Newton’s law
4. Murphy’s law

Explanation: According to Snell’s law Sin i/Sin r = constant

7. Twinkling of stars is due to which optical phenomenon?

1. Reflection
2. Interference
3. Refraction
4. Divergence

Explanation: A convex mirror always forms a virtual and smaller image irrespective of the position of the object. So, a full-length image of a distant tall building can definitely be seen by using a convex mirror.

8. The laws of reflection are valid for —————.

1. a convex mirror
2. a plane mirror
3. a concave mirror
4. all mirrors irrespective of their shape

Answer: (d) all mirrors irrespective of their shape

Explanation: The laws of reflection are valid for all mirrors irrespective of their shapes.

9. Light from the Sun falling on a convex lens will converge at —————.

2. Optical centre
3. Focus
4. None of the options

Explanation: Rays from the Sun converge at its focus after refraction through the convex lens.

10. Concave lens produces —————.

1. only virtual image
2. only erect image
3. only diminished image
4. virtual, erect, and diminished image

Answer: (d) virtual, erect, and diminished image

Explanation: Concave mirror has the ability to produce a virtual, erect, and diminished image.
