Orange light of wavelength 6000 × 10–10 m illuminates a single slit

1.	Orange light of wavelength 6000 × 10–10 m illuminates a single slit of width 0.6 × 10–4 m. The maximum possible number of diffraction minima produced on both sides of the central maximum is ____
Answer» For minima d sinθ = na For n to be maximum sinθ = 1 n = 6 x 10^-5/6 x 10^-7 = 100 Since n = 100 will corresponds to infinity. So No. of minima possible in one side is 99. And in both side it is 198

Orange light of wavelength 6000 × 10–10 m illuminates a single slit of width 0.6 × 10–4 m. The maximum possible number of diffraction minima produced on both sides of the central maximum is ____

Answer»

For minima

d sinθ = na

For n to be maximum sinθ = 1

n = 6 x 10^-5/6 x 10^-7 = 100

Since n = 100 will corresponds to infinity.

So No. of minima possible in one side is 99.

And in both side it is 198
