Wave Flashcard

Front

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

Back

Wavelength (λ) = Speed (v) / Frequency (f)

Front

What is frequency in the context of waves?

Back

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

Front

If a wave has a speed of 30 m/s and a frequency of 10 Hz, what is its wavelength?

Back

Wavelength = 30 m/s / 10 Hz = 3 m.

Front

What happens to the frequency of a wave if the wavelength increases?

Back

The frequency decreases.

Front

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

Back

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

Front

What is the unit of measurement for wavelength?

Back

Meters (m).

Front

Which wave has the highest frequency: a wave with a long wavelength or a wave with a short wavelength?

Back

A wave with a short wavelength has a higher frequency.

Front

What does a wave diagram typically represent?

Back

A wave diagram represents the amplitude, wavelength, and frequency of a wave.

Front

What is amplitude in the context of waves?

Back

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

Front

How does increasing the amplitude of a wave affect its energy?

Back

Increasing the amplitude increases the energy of the wave.
