Waves: Types & Properties

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the particle movement is perpendicular to the direction of wave propagation. Examples include light waves and waves on a string.

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave where the particle movement is parallel to the direction of wave propagation. Sound waves are a common example.

Front

What happens to wavelength when frequency increases?

Back

When frequency increases, the wavelength becomes shorter.

What is amplitude in the context of waves?

Back

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

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through (e.g., sound waves), while electromagnetic waves do not require a medium and can travel through a vacuum (e.g., light waves).

Front

What is the relationship between frequency and period?

Back

Frequency is the number of waves that pass a point in one second, while the period is the time it takes for one complete wave to pass. They are inversely related: Frequency = 1/Period.

What is a P-wave?

Back

A P-wave, or primary wave, is a type of longitudinal seismic wave that travels through the Earth during an earthquake.

What is a wave's medium?

Back

The medium is the substance through which a wave travels, such as air, water, or solid materials.

What is wave interference?

Back

Wave interference occurs when two or more waves overlap and combine to form a new wave pattern, which can be constructive (amplitudes add) or destructive (amplitudes subtract).

Front

What is the speed of a wave?

Back

The speed of a wave is the distance traveled by a wave in a given amount of time, calculated as Speed = Wavelength x Frequency.
