Question

Two of your friends made a sound. One strongly tapped the table while the other clapped his hands in the air. Which sound would you hear first? Justify your answer.

Answer: The sound is made from ___________________
Sound travels faster in ___________________​

Answer 1

The tapping on the table will be heard faster !

But why?

• One of the friends made a strong tab on the table and the other friend clapped his hands in the air.

• So, in the first case the sound wave is travelling as a pressure wave through the solid (i.e. table).

• In the 2nd case, the sound wave is travelling as a pressure wave through air.

Now, we know that speed of sound waves is much faster in solids ( approx 5-7 times) as compared to that of air.

So, the tap on table will be heard much faster as compared to the clap.
