Question

Two sound waves X and Y have the same amplitude and the same wave pattern but their frequencies are 60 Hz and 120 Hz respectively, then ______.

Options

• X will be shriller and Y will be grave

• X will be grave and Y will be shriller

• X will differ in quality than Y

• X is louder than Y

Answer 1

Two sound waves X and Y have the same amplitude and the same wave pattern but their frequencies are 60 Hz and 120 Hz respectively, then X will be grave and Y will be shriller.

Explanation:

Pitch is determined by the frequency of a sound wave. A higher frequency corresponds to a higher, or shriller, pitch, while a lower frequency results in a lower, or graver, pitch. Since wave Y has a higher frequency (120 Hz) than wave X (60 Hz), Y will be perceived as shriller and X as graver.
