Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

What are the two main types of mechanical waves?

Back

Transverse waves and longitudinal waves.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

What is amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, related to the energy of the wave.

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle displacement is perpendicular to the direction of wave propagation, while in longitudinal waves, the particle displacement is parallel to the direction of wave propagation.

What is a sound wave?

Back

A sound wave is a longitudinal mechanical wave that travels through matter, such as air, liquids, or solids.

What is an electromagnetic wave?

Back

An electromagnetic wave is a type of wave that does not require a medium to travel and can propagate through a vacuum.

What is intensity in terms of waves?

Back

Intensity is the power per unit area carried by a wave, often related to the amplitude of the wave.

What is a surface wave?

Back

A surface wave is a mechanical wave that travels along the interface between two different media, such as water waves.

What is the role of matter in wave propagation?

Back

Matter provides the medium through which mechanical waves, like sound and water waves, can travel.
