Answer 1

Answer:

Here's your answer

Explanation:

here's your diagram

1. Regular reflection occurs at the surface of a plane surface like a plane mirror. ... Diffused reflection occurs at the surface of a rough surface like cardboard. Reflected rays after regular reflection are not parallel. Note: Laws of reflection are valid in both the cases.

2.The first law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror, all lie in the same plane. The second law of reflection states that the angle of reflection is equal to the angle of incidence.

3. When two mirrors are placed at angles to each other we get multiple images because the image formed by one mirror acts as an object for the second mirror. Further images of an image are also formed. ... Two mirrors placed at right angles (90°) to each other will form actually 3 images

4. 35 images

5. Actually the Kaleidoscope is based on the principle of multiple reflection. according to this the light ray get reflected by these multiple mirror. when a light ray falls on one mirror , then it get reflected to the another one.

hope it helps
