Answer 1

3.two
4.irregular
plz mark as brainliest

Answer 2

• Two mirrors inclined to each other give multiple images.

- The number of images formed by two mirrors is dependent on the inclination angle between the two mirrors.

- Now,the number of images can be more than two images (90° inclination will make 3 images).

- So,it is better to say that the number of images formed by two inclined mirrors is multiple,as we don't know the angle of inclination.

• Diffused reflection takes place from irregular surfaces.

- In the diffused reflection,the light rays travel in random directions after getting reflected from the mirror surface.

- And,the random light reflection is only possible for irregular surfaces.
