Exam Review: Waves

Front

What is amplitude in the context of waves?

Back

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

Front

How does amplitude affect wave energy?

Back

Higher amplitude waves have more energy.

Front

What is the formula to calculate wave speed?

Back

Wave speed (v) = frequency (f) × wavelength (λ).

Front

Calculate the wave speed if the frequency is 5 Hz and the wavelength is 3 meters.

Back

15 m/s.

Front

What is a common property of all electromagnetic waves?

Back

They travel at the speed of light in a vacuum.

Front

What happens to a wave when it is reflected?

Back

It bounces back into the original medium.

Front

What is wave interference?

Back

Wave interference occurs when two or more waves meet and form a new wave pattern.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, the particle displacement is parallel to the direction of wave propagation; in transverse waves, it is perpendicular.

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.

Front

What is frequency in the context of waves?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).
