Question
In performing a microwave diffraction activity, you determined that the spacing between the atoms was given by d=λ/(2sinθ). Assuming a wavelength of λ=2.20 cm, if you measured the peak angle to be θ=25.0∘±3.5∘, what is the uncertainty in your measured separation due to the uncertainty in your measured angle?
