PS4.1-4.2 Test (Waves - Their Properties & Behaviors)

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 wavelength?

Back

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

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves have oscillations perpendicular to the direction of wave travel (e.g., light waves), while longitudinal waves have oscillations parallel to the direction of wave travel (e.g., sound waves).

Front

What is the amplitude of a wave?

Back

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

Front

What is frequency?

Back

Frequency is the number of waves 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 a trough in a wave?

Back

A trough is the lowest point of a wave, opposite to the crest.

Front

What is reflection in terms of waves?

Back

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

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another due to a change in speed.

Front

What is absorption in wave behavior?

Back

Absorption is the process by which a wave's energy is taken up by a material, converting it to other forms of energy.
