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 degree
2. 90 degree
3. 0 degree
4. 45 degree

Explanation: Since we know ∠i = ∠r for reflecting surfaces, angle of incidence is equal to angle of reflection.

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

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

Explanation: Refraction is the process which helps to focus light on the retina for good vision.

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

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

Explanation: The symbol to represent 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 option

Explanation: Convex mirror has the ability to produce an upright image and hence it is used in vehicles too.

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

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

Explanation: Snell’s law is given by Sin i/Sin r = constant

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

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

Explanation: Stars twinkle and sparkle due to many refractions that take place inside.

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 option
