Doppler's effect is used in:
Correct answer: C. RADAR sensors
- A. Leather industry
- B. Production of photographic supplies
- C. RADAR sensors
- D. None of these
Explanation
Doppler's effect is used in RADAR sensors to determine the velocities of objects far from the earth, this data is then used for analysis in astrophysics.It is also used in calculating the red or blue shift of distant stars and other objects in the space.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
