Sound and Light Waves

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 frequency?

Back

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

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs of a wave.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength have an inverse relationship; as frequency increases, wavelength decreases.

Front

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.

Front

What is the speed of a wave?

Back

The speed of a wave is calculated by the formula: speed = frequency × wavelength.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which 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 wave in which the particles of the medium move perpendicular to the direction of the wave's travel.

Front

What is sound?

Back

Sound is a type of mechanical wave that travels through a medium (solid, liquid, or gas) and is produced by vibrating objects.

Front

What is light?

Back

Light is an electromagnetic wave that can travel through a vacuum and does not require a medium.
