A single slit of width b is illuminated by a coherent monochromatic light of wavelength λ. If the second and fourth minima in the diffraction pattern at a distance 1 m from the slit are at 3 cm and 6 cm respectively from the central maximum, what is the width of the central maximum? (i.e. distance between first minimum on either side of the central maximum)
  • a)
    1.5 cm
  • b)
    3.0 cm
  • c)
    4.5 cm
  • d)
    6.0 cm
Correct answer is option 'A'. Can you explain this answer?

Λ. The angle between the diffraction maximum of order m and the central maximum is given by the formula:

sinθ = mλ/b

where θ is the angle, m is the order of the diffraction maximum, λ is the wavelength of the light, and b is the width of the slit. This formula is known as the single slit diffraction formula.
