Question

An object is viewed through a glass prism with its
vertex pointing upwards. Draw a ray diagram to
show the formation of its image as seen by the
observer.​

Answer 1

Answer:

 phenomenon in which a ray of light deviates from its original path, while travelling from one optical medium to another optical medium.

Explanation:

The rays coming from the face of person, sitting across the camp fire, suffer refraction on passing through hot air. Thus, we see apparent image of person. Since hot air is in motion, therefore its optical density changes, which in turn shifts the image rapidly. This rapidly shifting image gives a shimmering effect.
