Waves

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through a vacuum and do not require a medium. Examples include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

Which types of materials can sound travel through?

Back

Sound can travel through solids, liquids, and gases.

Front

What are mechanical waves?

Back

Mechanical waves are waves that require a medium (solid, liquid, or gas) to travel through. Examples include sound waves and water waves.

Front

Define a wave in the context of physics.

Back

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

Front

What happens to the wavelength when the frequency of a wave increases?

Back

When the frequency of a wave increases, the wavelength decreases.

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.

Front

What is the trough of a wave?

Back

The trough is the lowest point of a wave.

Front

What is the relationship between frequency and wavelength in waves?

Back

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

Front

What is the speed of a wave?

Back

The speed of a wave is the distance it travels per unit of time, often calculated using the formula: speed = frequency × wavelength.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the particle displacement is perpendicular to the direction of wave propagation, such as in light waves.
