Question:

Coherent electromagnetic waves with wavelength λλ pass through a narrow slit of width aa. The diffraction pattern is observed on a tall screen that is 2.00 mm from the slit. When λ=500nmλ=500nm, the width on the screen of the central maximum in the diffraction pattern is 8.00 mmmm.

For the same slit and screen, what is the width of the central maximum when λ=0.125mmλ=0.125mm?

2y=?


Answers

for Diffraction, the width of control maxima is by Given k W, = 21,D a. = 2120 wz 2 au W2= Wido = 8mm x 0.125 mm Soo X10-9 Afor Diffraction, the width of control maxima is by Given k W, = 21,D a. = 2120 wz 2 au W2= Wido = 8mm x 0.125 mm Soo X10-9 A
