Questions
Light of wavelength 6000 is incident normally on a slit of width cm. Find out the angular position of second minimum from central maximum
detailed solution
Correct option is C
For 2nd minimum, asinθ=2λ put λ=6×10−7m, a=24×10−5×10−2m ⇒sinθ=2λa=2×6×10−724×10−7=12 ∴θ=300Talk to our academic expert!
