Answer 1

Answer:

A

Explanation:

Huygens principle....

Answer 2

Answer:

A

Explanation:

When a ray of light passes from a rarer medium to a denser medium, or it passes from a less dense to a optically denser medium , it bends toward the normal and if it passes from a denser medium to a rarer medium or from an optically dense medium to a less dense medium , the ray will bend away from the normal. Its speed decreases while travelling from a rarer medium to a denser medium and increase while travelling from a denser medium to a rarer medium.
