Explanation 1) Concept: We can apply Doppler Effect for approaching and reflecting waves and get two equations. Solving them, we can get the speed of the target object. 2) Formula: i) f ' = f × v v - v s ii) f ' = f × v + v D v 3) Given: i) The frequency emitted by the transmitter is f = 18.0 k H z = 1.8 × 10 4 H z ii) The frequency detected by the detector is f ' = 22.2 k H z = 2.22 × 10 4 H z 4) Calculations: Let us assume that the target is the detector. We have the equation of Doppler Effect for stationary source and moving detector when the detector moves toward the source as f ' = f × v + v D v f 1 = 1.8 × 10 4 × 343 + u 343 Now, we consider the reflected wave from the target as the source wave. We have the equation of Doppler Effect for stationary detector and moving source when the source is moving towards the detector as f ' = f × v v - v s 2

Electromagnetic Waves

Electromagnetic waves are waves that consist of magnetic field and electric field components perpendicular to each other. These field components are also perpendicular to the direction of propagation of the wave.
