Question

Write T for true and F for false statements.
1. The bouncing back of light into its original medium after striking a surface is called
refraction of light.
2. When a parallel beam of light strikes a rough surface, the light rays reflects in different
directions producing diffused reflection.
3. The angle of incidence is always equal to angle of reflection.
4. The image of the right hand in a plane mirror looks like left hand.
5. A virtual image may be inverted or erect.
6. The image formed by a plane mirror is a real image.
7. In irregular reflections, we can see objects clearly,
8. The image formed by a plane mirror is diminished.

Answer 2

1. FALSE, bouncing back of light into its original medium after striking a surface is called REFLECTION OF LIGHT.
2. TRUE, When a parallel beam of light strikes a rough surface, the light rays reflect in different directions producing DIFFUSED REFLECTION.
3. TRUE, The angle of incidence is always EQUAL to the angle of reflection according to the law of reflection of light.
4. TRUE, The right-hand image in a plane mirror looks like the left hand due to LATERAL INVERSION.
5. FALSE, A virtual image is always erect.
6. FALSE, The image formed by a plane mirror is a VIRTUAL image.
7. FALSE, In irregular reflection, we cannot see the clear image as they form a blurry image.
8. FALSE, the image formed by a plane mirror is always of the SAME SIZE as that of the object.
