Waves and Sound

Front

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

Back

The wavelength decreases.

Front

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

Back

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

Front

If a wave has a wavelength of 10 m and a speed of 340 m/s, what is the frequency?

Back

34 Hz

Front

Which wave has the greatest frequency in a diagram?

Back

The wave with the shortest wavelength has the greatest frequency.

Front

What is refraction in the context of waves?

Back

Refraction is the bending of a wave as it passes from one medium to another.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is the speed of sound in air at room temperature?

Back

Approximately 340 m/s.

Front

What is the longest wavelength in a set of waves?

Back

The wave with the lowest frequency has the longest wavelength.

Front

What is interference in wave behavior?

Back

Interference is the phenomenon that occurs when two waves meet and combine.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of a wave when it hits a barrier, while refraction is the bending of a wave as it enters a different medium.
