Questions and Answers

What are waves?

Waves are disturbances or vibrations that travel from one point to another, characterized by a transfer of energy.

What are the two types of waves based on the direction of propagation?

The two types of waves based on the direction of propagation are transverse waves and longitudinal waves.

Give an example of a transverse wave.

Light is an example of a transverse wave.

Give an example of a longitudinal wave.

Sound waves are an example of longitudinal waves. Signup and view all the answers

What are mechanical waves?

Mechanical waves are waves that require a medium to propagate, such as waves produced on a string or a slinky. Signup and view all the answers

What is vibration?

Vibration is the repeated back-and-forth motion of a particle when displaced from its equilibrium position. Signup and view all the answers

Give an example of vibration.

Examples of vibrations include the vibration of a tuning fork, the swinging of a pendulum, and the oscillation of a radio's loudspeaker. Signup and view all the answers

How is sound produced from vibrations?

When a source vibrates, it displaces the particles in the medium, allowing it to move back and forth parallel to the direction of the wave. The repeated vibration of the particles then reaches human ears and is interpreted by the brain as sound. Signup and view all the answers
