The air temperature is 92 degrees Fahrenheit. A truck is honking its horn as it is traveling at 30 mph away from you. The truck horn has a frequency of 1197 Hz. What is the frequency you hear the horn as having? Do not round off the  term. The perceived frequency is [x] ______________________ Hz

A sound wave in a solid has a frequency of 45.0 kHz and a wavelength of 0.333 m. What would be the wave speed, and how much faster is this speed than the speed of sound in air? (The speed of sound in air is 344 m/s.) speed of sound in solid       speed of sound in solid speed of sound in air

A bat can detect small objects, such as an insect, whose size is approximately equal to one wavelength of the sound the bat makes. If bats emit a chirp at a frequency of 51.0 kHz, and if the speed of sound in air is 340 m/s, what is the smallest insect a bat can detect?mm

Going down the road at 65 miles per hour on a 86.0 °F summer day, Bari heard a siren approaching. Bari knows that a police siren's frequency is 1280.0 Hz, but it didn't sound like that. Bari pulled over a lane, without slowing down, after seeing the flashing lights of the police car coming up from behind, and the police passed going 25 miles per hour faster than Bari was going. (1 mile = 1.60 km) a) what was the speed of sound on that warm summer day? b) How fast, in m/s, was the police car going? c) What frequency did Bari hear from the siren before the police car passed? d) What frequency did Bari hear from the siren after the police care had passed?
