Wavelength doesn't look right.
I don't know how you got 10^-4 but you must use the info that there are 11 nodes and the distance between 1st and 11th node is 14cm

I got 10-4 because I thought my textbook mentioned microwaves had wavelengths at about 10-4. Um. I'll give it another go. Thanks.

There is a range of values for wavelengths.
Why would they bother giving those info if you don't need them? :tongue:

Is the answer 1.07x10 ^10?
