Two radio towers are positioned 10m apart. They emit waves of 750mHz. How many maxima will you detect if you walk around the towers in a circle of radius=10m?(adsbygoogle = window.adsbygoogle || []).push({});

I know that the path length difference, [tex]\Delta r [/tex], must = an integer number of wavelengths:

[tex] \Delta r = n\lambda [/tex]

Where I'm confused is how to find an expression using this information to solve for the number of maximas in a circle. Can anyone give me any hints? I'd show more work if I could think of anything else. The only other work I have is solving for the wavelength:

[tex] c = \lambda f [/tex]

[tex] \lambda = \frac{c}{f} = \frac{3X10^8m/s}{750000000Hz} = .4m [/tex]
