Question

1. Define the reflection of light.
2. State the laws of reflection,
3. If the angle of reflection is 45°, what is the angle between the incident ray and the
reflected ray?
4. Draw the incident ray and the reflected ray, if a light ray is incident on a plane mirror
with the angle of incidence 30°.
5. What are the characteristics of images formed by a plane mirror?
6. What are the uses of a plane mirror?
7. What do you mean by lateral inversion of an image?
8. How do you get secondary colours by colour addition?​

Answer 1

Answer:

The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface. ... Light is diffused when it reflects from a rough surface.

Answer 2

Answer:

1-The bouncing back of ray if light after striking any reflecting surface is known as reflection of light.

2-All incident,normal and reflected rays lies on same plane.

Angle of incidence is equal to angle of reflection.

3- 90 degree

5-image is virtual,erect,same size of objects, laterally inverted.

Explanation:

6-plane mirror used as face mirror

it also used in shops for protecting from robbery.

7-The phenomenon in which right side part seen in left and left side part seen in right in , This phenomenon is known as lateral inverted.
