Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter.

Front

What are mechanical waves?

Back

Mechanical waves are waves that require a medium (solid, liquid, or gas) to travel through, such as sound waves and ocean waves.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that do not require a medium and can travel through a vacuum, caused by disturbances in electric and magnetic fields.

Front

What is the relationship between frequency and pitch?

Back

As frequency increases, pitch rises (goes higher).

Front

Do all electromagnetic waves travel at the same speed?

Back

Yes, all electromagnetic waves travel at the speed of light in a vacuum.

Front

What is wavelength?

Back

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

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 difference between transverse and longitudinal waves?

Back

In transverse waves, the particle displacement is perpendicular to the direction of wave propagation (e.g., light waves), while in longitudinal waves, the particle displacement is parallel to the direction of wave propagation (e.g., sound waves).

Front

What is the speed of a wave?

Back

The speed of a wave is determined by the product of its frequency and wavelength (Speed = Frequency x Wavelength).

Front

What is a medium in the context of waves?

Back

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