I want to know how to tweak with the relationships to get any of the unknown values. Could you please show me how?

How did you know the wave length (λ) when you said "Δ x ≈ D λ / d which gives Δ x ≈ 0.161 m Δx≈0.161m." ? I have been trying to solve for it. Also why is the frequency 93 GHz when it is 3.0 * 10^9 Hz? Thank you.

I drew a diagram

Hello sir. I've spent literally 4 hours trying to solve this. Basically the given variables are wavelength = ? velocity = ? delta x (nodal line distance) = ? f = 3.0 * 10^9 Hz d = 2.0 m L = 1.0 * 10^2 m t = 0.20 s The equations that are relevant are v = f * wavelength (universal wave...

Homework Statement [Answer is V = 25m/s, however, how do I get that answer? Thank you!] A police cruiser sets up a novel radar speed trap, consisting of two transmitting antennas at the edge of a main north-south road. One antenna is 2.0 m [W] of the other. The antennas, essentially point...
