To Find: The speed of the moving object with respect to the radar.
Answer to Problem 65A
The velocity of the object is 26.365 m/s .
Explanation of Solution
Given:
Frequency of transmitter = 10.525 GHz
Doppler shift frequency = 1850 Hz
Formula:
The equation of velocity in Doppler Effect
Vtarget=cfDoppler2ftransmitted ...... (1)
Here fDoppler is the Doppler shift frequency, ftransmitted is frequency of transmitted wave, Vtarget is the velocity of target and c is the speed of light.
Calculation:
Substitute 1850 Hz for fDoppler , 10.525 GHz for ftransmitted in equation (1)
Vtarget=cfDoppler2ftransmitted= 3×108×18502×10.525×109= 26.365 m/s
Conclusion:
Hence, the required velocity of the object is 26.365 m/s .

A student performed an experiment in an attempt to determine the index of refraction of glass. The student used a laser and a protractor to measure a variety of angles of incidence and refraction through a semi-circular glass prism. The design of the experiment and the student's results are shown below.
