Experiment to Observe Speed of Sound | Bell Jar Experiment | Physics| Letstute

Hi friends,

Let’s start this session with something fun!!

This video is based on Speed of Sound how does medium affects the speed of sound.

You all must have seen fireworks. We all love them. All the colors and patterns in the sky! The view is mesmerizing. However, did you notice one thing here?

You see fireworks before, and you hear the sound of bursting of crackers later. Why does this happen?

This happens because light travels faster than sound.

In order to see the change in speed of sound, we will use three media, Air, water and Solid.

The experiment that we performed in air is called as Bell Jar Experiment. In this experiment we will conclude that sound needs a medium to travel and cannot travel in vacuum.

Second medium is water, we submerge our sound system in water and we conclude that the speed of sound is 4 times higher in water when compared with air and is louder in water when compared with air.

Last medium that we used is a solid rod, and conclusion was breathtaking. Speed of sound is almost 15 times higher in solids when compared to air.
