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 are the two main types of mechanical waves?

Back

Transverse waves and longitudinal waves.

Front

What is a transverse wave?

Back

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

Front

What is a longitudinal wave?

Back

A wave in which the particles of the medium move parallel to the direction of the wave's travel.

Front

What is an electromagnetic wave?

Back

A wave that can travel through matter and empty space, consisting of oscillating electric and magnetic fields.

Front

What is the speed of light in a vacuum?

Back

Approximately 299,792 kilometers per second (or about 300,000 kilometers per second).

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is amplitude in a wave?

Back

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

Front

What is the medium in the context of waves?

Back

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

Front

Why can't sound travel in outer space?

Back

Sound requires a medium to travel through; in outer space, there is no medium.
