wavelength=2(15mm)=.03m
freq=3E8/3E-2=10ghz
Hi, I need help with another question!
A microwave transmitter emits waves towards a metal plate. The waves strike the plate and are reflected back along their path.
I really wish I could put the diagram here but I don't think that's possible... The diagram shows 5 nodes (TSRQP), where minima of intensity is observed. These points are 15 mm apart. What is the frequency of the microwave?

Answer is 10GHz but I got 6.7GHz :C
What I did:
I assumed that frequency is for the 4th harmonic. So, I did: F=(2*15)/4.5
How do I do this?
