1. The speed of light is more in air(or vaccum) than in glass or water.


2. When a wave enters from one medium to another its freqency does not change.


3. The law of reflection of water waves is not identical to law of reflection of light.


4. A body executing simple harmonic motion, always vibrates about its position of equilibrium.


5. The snake like motion of the rope is the example of
