Question

The Young's double slit experiment is performed with blue and with green light of wavelengths 4360Å and 5460Å respectively. If x is the distance of 4th maxima from the central one, then:

विकल्प

• x (blue) = x (green)

• x (blue) > x (green)

• x (blue) < x (green)

• `("x"("blue"))/("x"("green")) = 5460/4360`

Answer 1

x (blue) < x (green)

Explanation:

Distance of nth maxima, x = `"n"λ"D"/"d" ∝ λ`

As λ_b < λ_g

∴ x_blue < x_green
