Sound
Why is the speed of sound greater in solids than in gases?
Sound
A sound wave of frequency 500 Hz travels in air at 340 m s−1. Calculate its wavelength.
Sound
Resonance occurs when the frequency of the applied periodic force is:
Sound
A person standing 165 m from a cliff claps and hears the echo after 1 second. Calculate the speed of sound in air.
Sound
A person claps and hears the echo from a cliff after 2 seconds. If the speed of sound is 340 m s−1, find the distance of the cliff.
