We know from experience that the Doppler shift of sound from a moving car is easily detectable. Assuming light with a frequency of 10×1014 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 150 m/s.

We know from experience that the Doppler shift of sound from a moving car is easily detectable. Assuming light with a frequency of 5×1014 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 140 m/s.
The speed with which blood flows through an artery can be determined from the Doppler shift...
The speed with which blood flows through an artery can be determined from the Doppler shift in high-frequency sound waves sent into the artery and detected after reflection from the moving blood cells. What is done is to aim the source and receiver of the sound so that the reflections occur from cells moving away from them. Thus, the sound waves striking a cell are Doppler shifted because of its motion away from the source, and the waves that reach...

Police radar determines the speed of motor vehicles using the same Doppler-shift technique employed for ultrasound in medical diagnostics. Beats are produced by mixing the double Doppler-shifted echo with the original frequency. If 2.25 ✕ 1010 Hz microwaves are used and a beat frequency of 2,400 Hz is produced, what is the speed (in m/s) of the vehicle? (Assume the same Doppler-shift formulas are valid with the speed of sound replaced by the speed of light.)

The police use radar guns and the Doppler effect to catch violators. A police car is driving from right to left at 50 km / h, another man's car is driven at a speed of 150 km / h away from the police car in the same direction. A police radar gun emits an electromagnetic wave whose frequency is 5.0 × 107 Hz that is reflected from the oncoming car. What is the difference between the frequency of the wave...

A doppler fetal monitor is a hand-held ultrasound device that is used to detect a fetal heartbeat in prenatal care. The device works by measuring the speed of the fetus's ventricular wall and thereby tracking its heartrate. a. Suppose the fetus's ventricular wall moves back and forth in a pattern approximating simple harmonic motion with an amplitude of 1.7 mm and a frequency of 3.0 Hz. Find the maximum speed of the heart wall (in m/s) during this motion. Be...

A speaker on a car produces a 150 Hz sound wave when parked. The car starts to drive toward a pedestrian standing by the road, and the pedestrian hears the sound shift to 160 Hz when the car starts to drive toward them. The car passes the pedestrian and drives away from them. What frequency would the pedestrian hear as the car drives away? Assume the speaker continuously produces the same frequency, the car maintains the same speed, and the...
