1. The problem statement, all variables and given/known dataA radar transmitter used to measure the speed of pitched baseballs emits pulses of 2.0 cm wavelength that are .25 μs in duration. a) What is the length of the wave packet produced? b) To what frequency should the receiver be tuned? c) What must be the minimum bandwidth of the receiver? 2. Relevant equations ΔkΔx≈1 ΔωΔt≈1 3. The attempt at a solution Part c) was easy enough. ΔωΔt≈1 → Δω≈1/Δt = 1/.00000025 = 4000000 4000000/2π = 6.36e5 Hz The others? I have no idea. The section of the text barely defines what a wave packet is and I've read through it at least three times. I would appreciate some help getting started.
