Hi all, I have a question here that I've done but it hasn't got an answer provided. I'm sure it's easy stuff but haven't looked at this material in a while so
just want to double check.
(The things in red are what I added to the original diagram)
RE-DONE
d = √17
d + λ/2 = 2√5
λ/2 = 2√5 -d
λ = 4√5 -2(√17)
λ = 0.698m
Using v=fλ
∴f = 340/0.698 = 487 Hz
Is this correct?
Thanks in advance
