Unit 5 Test: Waves

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength have an inverse relationship. If the frequency of a wave decreases, the wavelength increases.

Front

What is periodic motion?

Back

Periodic motion is motion that repeats at regular intervals, such as the swinging of a pendulum or the vibrations of a guitar string.

Front

What formula is used to calculate wavelength?

Back

Wavelength (λ) can be calculated using the formula: λ = v/f, where v is the speed of the wave and f is the frequency.

Front

What causes waves?

Back

Waves are caused by oscillations, which are repeated back-and-forth movements.

Front

What happens when waves travel from one medium to another?

Back

When waves travel from one medium to another, they undergo refraction, which is the bending of waves due to a change in speed.

Front

Define wavelength.

Back

Wavelength is the distance between successive crests (or troughs) of a 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 speed of a wave?

Back

The speed of a wave is the distance traveled by a wave in a given amount of time, calculated as speed = wavelength × frequency.

Front

What is reflection in the context of waves?

Back

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

Front

What is interference in wave behavior?

Back

Interference is the phenomenon that occurs when two or more waves overlap and combine to form a new wave pattern.
