Waves Test

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter, typically characterized by its amplitude, wavelength, frequency, and speed.

Front

Define amplitude in the context of waves.

Back

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

Front

What is wavelength?

Back

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

Front

Explain frequency in relation to waves.

Back

Frequency is the number of complete wave cycles that pass a given point in one second, measured in hertz (Hz).

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 diffraction?

Back

Diffraction is the bending of waves around obstacles or through openings, which causes the waves to spread out.

Front

What is reflection in wave behavior?

Back

Reflection is the bouncing back of a wave when it encounters a barrier or a different medium.

Front

Define refraction.

Back

Refraction is the change in direction of a wave as it passes from one medium to another due to a change in speed.

Front

What is an electromagnetic wave?

Back

An electromagnetic wave is a type of wave that can travel through a vacuum and does not require a medium, such as light or X-rays.

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium (solid, liquid, or gas) to travel through, such as sound waves.
