Question

a)The range of human hearingextends from approximately 20 Hz to 20000 Hz. Find the wavelengthfor 20 Hz when the speed of sound in air is 335 m/s. Answer inunits of m. b)Find the wavelengthfor 20000 Hz when the speed of sound in air is equal to 335m/s.Answer in units of m. a)The range of human hearingextends from approximately 20 Hz to 20000 Hz. Find the wavelengthfor 20 Hz when the speed of sound in air is 335 m/s. Answer inunits of m. b)Find the wavelengthfor 20000 Hz when the speed of sound in air is equal to 335m/s.Answer in units of m.

Explanation / Answer

given that     frequency = f1 = 20HZ     speed of sound = v = 335m/s wave length of sound wave = v/f1 =335m/s/20HZ = 16.75m    simillarly f2 = 20000HZ then = v/f2 = 335m/s/20000HZ =0.01675m
