Statement I : 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 II : In the double slit experiment the fringe width depends directly on the wavelength of light.

View answer and explanation

Correct option: A

Statement I is true, Statement II is true; Statement II is the correct explanation for Statement 4

Option A (Statement I is true, Statement II is true; Statement II is the correct explanation for Statement 4) is correct because fringe width is directly proportional to wavelength, affecting the number of fringes observed.
