Answers
Answer:
Sound is a mechanical wave that needs a material medium like air, water, steel, etc., for its propagation. A sound wave travels in the form of a longitudinal wave and it requires a material medium for its propagation. Sound always originates from some vibrating body. These vibrations are produced by tuning forks, drums, bells, the strings of a guitar, etc. The bell jar experiment is a common experiment used to demonstrate that sound needs a medium to travel. A bell jar is a laboratory equipment used for creating a vacuum. It is so named as its shape is similar to that of a bell. A bell jar is placed on a base which is vented to a hose fitting that can be connected via a hose to a vacuum pump.
Answer:
No sound doesn't travel in absence of medium.
