Wave Properties Flashcard C

Front

What is the formula to calculate the period of a wave?

Back

Period (T) = 1 / Frequency (f)

Front

Define frequency in the context of wave properties.

Back

Frequency is the number of cycles of a wave that occur in one second, measured in Hertz (Hz).

Front

What is the relationship between wave speed, frequency, and wavelength?

Back

Wave speed (v) = Frequency (f) × Wavelength (λ)

Front

If a wave has a frequency of 0.25 Hz, what is its period?

Back

4 seconds

Front

What happens to the wavelength of a wave if its frequency doubles while the speed remains constant?

Back

The wavelength halves.

Front

What is the definition of amplitude in wave properties?

Back

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

Front

How do you calculate the depth of a lake using the time it takes for a sonic pulse to return?

Back

Depth = (Speed of sound × Time) / 2

Front

What is the term for the time taken to complete one full cycle of a wave?

Back

Period.

Front

If Olive completes a swing cycle every 4.0 seconds, what is the frequency of her swing?

Back

Frequency = 1 / Period = 0.25 Hz.

Front

What is the unit of measurement for frequency?

Back

Hertz (Hz).
