In a YDSE the separation between the slits is 1 mm and the screen is at a distance of 2 m from the plane of the slits. The wavelength missing on the screen at a point directly in front of one of the slits is:
Correct answer: B. 500 nm
- A. 417 nm
- B. 500 nm
- C. 523 nm
- D. 600 nm
Explanation
The correct approach involves using the formula for path difference in Young's Double Slit Experiment, which leads to the missing wavelength at the point in front of one of the slits being 500 nm. Option A, C, and D do not yield the accurate result when the formula is applied, making them incorrect choices.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
