Waves and Wave Interactions

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is reflection in wave interactions?

Back

Reflection is the bouncing back of a wave when it hits a barrier.

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

What is frequency?

Back

Frequency is the number of waves that pass a given point in a specific amount of time, usually measured in Hertz (Hz).

Front

What happens to the wavelength as frequency increases?

Back

As frequency increases, the wavelength decreases.

Front

What is wave speed?

Back

Wave speed is the distance a wave travels per unit of time, calculated as wave speed = frequency × wavelength.

Front

What is amplitude?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as one increases, the other decreases.

Front

What is refraction?

Back

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

Front

What is diffraction?

Back

Diffraction is the spreading out of waves when they pass through an opening or around obstacles.
