This question has Statement \(-1\) and Statement \(-2.\) Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement \(-1:\) In Young's double slit experiment, the number of fringes observed in the field of view is small With longer wavelength of light and is large with shorter wavelength of light. Statement \(-2:\) In the double slit experiment the fringe width depends directly on the wavelength of light.
Pick an option to check your answer.
Answer & Solution
Correct Answer
(C) Statement \(- 1\) is true Statement \(-2\) is true and the Statement \(-2\) is not correct explanation of the Statement \(- 1\).
Step-by-step Solution
Detailed explanation
Fringe width \(\mathrm{B}=\frac{\mathrm{D}}{\mathrm{d}} \lambda\)
And number of fringes observed in the field
of view is obtaincd by \(\frac{d}{\lambda}\)
