How fast, in kilometers per hour, must a sound source be moving toward you to make the observed frequency greater than the true frequency? (Assume that the speed of sound is 340 m/s.)
Answer to relevant QuestionsYou are driving east at 25.0 m/s as you notice an ambulance traveling west toward you at 35.0 m/s. The sound you detect from the sirens has a frequency of 300 Hz. (a) Is the true frequency of the sirens (1) greater than 300 ...An observer is traveling between two identical sources of sound (frequency 100 Hz). His speed is 10.0 m/s as he approaches one and recedes from the other. (a) What frequency tone does he hear from each source? (b) How many ...The human ear canal is about 2.5 cm long. It is open at one end and closed at the other. (a) What is the fundamental frequency of the ear canal at 20 oC? (b) To what frequency is the ear most sensitive? (c) If a ...An organ pipe that is closed at one end is filled with helium. The pipe has a fundamental frequency of 660 Hz in air at 20oC. What is the pipe’s fundamental frequency with the helium in it? An unstretchable steel string is used to replace a broken violin string. A length of 5.00 m of this string has a mass of 25.0 g. When in place, the new string will be 30.0 cm long and oscillate at 256 Hz in its fundamental ...
