Answer 2

The given statement is FALSE.

- Light travels with different speeds in different media.

- When it is incident normally on the interface of two media, then its direction will not change.

- But its speed will change according to the media.

- If the second medium is denser than the first medium, then the speed of light will become slower.

- If the second medium is rarer than the first medium, then the speed of light will become faster.
