Look at the two wave diagrams. which best describes the difference between wave a and wave b? wave a has a greater pitch and frequency. wave b has a greater pitch and frequency. wave a has a greater pitch but lower frequency. wave b has a lower pitch but greater frequency

A, Wave A has a greater pitch and frequency.

Explanation:

Did the test on edg!

Correct answer is Wave A has a greater pitch and frequency

Explanation:

To understand the given figure, we should know the definition of wavelength, frequency and pitch

Wavelength

wavelength is defined as distance between two successive wave crests or troughs.

Frequency

Frequency is defined as the number of waves which passes through a given point per second. SI unit of frequency is Hertz.

Pitch

our ear understand the frequency of a sound wave as pitch. A a lower frequency sound has a lower pitch and a higher frequency sound has a higher pitch.

In given figure Wave A has lower wavelength and higher frequency so it have higher pitch than wave B.
