Question

how sound wave travels transversely.

Answer 1

Hello user !!

Here's the answer you are looking for

Sound is a longitudinal wave that requires a medium to travel (as it travels by setting the particles of the medium into vibration).


Here's how it travels.....

Let's assume that sound is produced by a speaker. That means it's flaps must be vibrating. Because vibrations produce sound.

Now while vibrating, when the flap comes outwards, it compresses the air column present infront of it...... As a result the air in that region also start vibrating..... Since the air is compressed this region is known as compression.

Then when the flap moves back the air column also moves back..... As a result the air particles move away from each other..... And this forms a rare fraction....

Now in the first case when the air particles were vibrating in the compression region, they passed on their disturbance and set the lying next to it into vibration.....

This transfer of disturbance continued.....hence making the sound waves travel in the medium... !!

This is a continuous process. Compressions and rare fraction form continuously and the disturbance also created continuously...
