A student is standing 500 meters away from a cliff. They shout towards the cliff, and the echo returns after 2.5 seconds. Calculate the speed of sound in the air, assuming it travels back and forth between the student and the cliff. A sound wave with a frequency of 800 Hz is produced by a tuning fork. If the wave travels through air at a speed of 340 m/s, what is the wavelength of the sound wave?A guitar string is plucked, producing a sound wave with a frequency of 440 Hz and a wavelength of 0.75 m. Calculate the speed of the wave as it travels through the guitar string
