Energy & Waves

Front

What is energy?

Back

Energy is the ability to do work or cause change. It can exist in various forms, such as kinetic, potential, thermal, and more.

Front

What is a wave?

Back

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

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave where the particles of the medium move parallel to the direction of the wave's travel.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the particles of the medium move perpendicular to the direction of the wave's travel.

Front

What is a medium in the context of waves?

Back

A medium is the matter (solid, liquid, or gas) through which waves can travel.

Front

What is the primary purpose of waves?

Back

Waves are primarily used for transferring energy.

Front

What is a compressional wave?

Back

A compressional wave, also known as a longitudinal wave, is a wave in which the particles of the medium are compressed and then rarefied.

Front

What is a sound wave?

Back

A sound wave is a type of mechanical wave that travels through a medium (like air, water, or solids) and is perceived as sound.

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.

Front

What is frequency?

Back

Frequency is the number of waves that pass a given point in one second, measured in hertz (Hz).
