radargun usesthe Doppler shift in order toseehow fast acar is going. If the radiowaves have a frequency of 157kHznormally, and thegun detects the reflectedwavelength off of a car to be1850m, how fast is thespeeding cargoing? the speed of the wave is 3*10^8m/s.

We know from experience that the Doppler shift of sound from a moving car is easily detectable. Assuming light with a frequency of 9×1014 Hz, calculate the Doppler shift (the difference of the observed and emitted frequencies) for light from a car moving toward you at a speed of 220 m/s.

The Doppler shift was first tested in 1845 by the French scientist B. Ballot. He had a trumpet player sound a 422 Hz note while riding on a flat-car pulled by a locomotive. At the same time, a stationary trumpeter played the same note. Ballot heard 3 beats/s. How fast was the train moving toward him? The speed of sound in air is 343 m/s. Answer in units of m/s.

In order to get going fast, eagles will use a technique called stooping, in which they dive nearly straight down and tuck in their wings to reduce their surface area. While stooping, a 6-kg golden eagle can reach speeds of up to 53 m/s. While golden eagles are not very vocal, they sometimes make a weak, high-pitched sound. Suppose that while traveling at maximum speed, a golden eagle heads directly towards a pigeon while emitting a sound at 1.1 kHz....

Doppler Effect: 1. A stationary police officer using a speed “radar detector” sends a signal with a frequency of 100,000 Hz. The speed of sound is 340 m/s. What is the wavelength of the (ultra) sound wave produced by the detector? The sound wave reflects off a vehicle moving toward the officer. How does the frequency of the reflected sound wave (as recorded by the detector) compare to the original sound wave? 2. The light waves from a distance start...

a Doppler ultrasound machine can measure blood flow speeds, for instance, in a patient’s artery. The probe is illustrated below. First, here are two questions about the Doppler effect: When a listener is moving away a stationary source that emits a sound wave of frequency f, the listener will hear a sound of   ["smaller frequency", "the same frequency", "greater frequency"]           When a source that emits a sound wave of frequency f moves away a stationary listener, the listener...
