Q. A light ray interacts with the matter around in several ways. Which of the following are the correct observations?
- a ray of light bends when it enters from one medium to another
- a ray of light bounces off a surface in such a way that the incident ray, normal and the reflected ray are in the same plane
- a ray of light after striking some surfaces, gets absorbed by them
- A ray of light doesn’t follow the property of rectilinear propagation in a medium other than vacuum
