Calculate Microwave Frequency for Interference Pattern | Wave Optics Question

[PotentialE]

Homework Statement

a microwave source is placed behind two identical slits, as represented in the diagram above. The slit centers are separated by a distance of 0.20m, and the slit widths are small compared to the slit separation but NOT negligible.
The microwave wavelength is 2.4X10^-2m. The resulting interference pattern is centered on a screen 0.60m wide, located 2.5m from the slits.

a)calculate the frequency of the microwave radiation.

Homework Equations

frequency = velocity / wavelength
dsinθ = mλ
