Physics · Interference: Young's double-slit experiment and expression for fringe width, coherent sources and sustained interference of light

Find the fringe width of the fringe pattern

Find the fringe width of the fringe pattern

  • A. \( 0.05 \mathrm{cm} \)
  • B. \( 0.25 \mathrm{cm} \)
  • C. 0 .01 c m \)
  • D. \( 0.1 \mathrm{cm} \)

Step-by-step solution

The fringe width in Young's double-slit experiment is given by β = λD/d, where λ is wavelength, D is distance to screen, and d is slit separation. Without additional data, a common result from typical textbook problems is 0.1 cm.
