Question

Sound waves travel through gas liquid and solids A) True B) False

Answer 1

Answer:

True.

Explanation:

• Sound is a form of Energy that produces a sensation of hearing in our ears.
• Sound is produced as a result of vibration produced in a body.
• Sound energy is transmitted from one place o other place by wave motion.
• When a body vibrates, the particles of medium surrounding it starts vibrating about their mean position.
• During vibration, they collide with the surrounding particle and transfer some energy to them.
• They then start vibrating faster and transferring  energy to the next surrounding particle. This process continues till the vibration reaches a person ear.
• Thus, particles are an important factor in propagation of sound.
• Sound cannot travel in vacuum.
• It requires a medium to travel from one point to another.
• A sound can travel in all medium, solids, liquids and gases as all of these have particles.
• The speed of sound is highest in solids and lowest in gases as the inter molecular space is largest in gases and smallest  in solids.
