The reason there are two slits, rather than one, in a Young's experiment is:
Correct answer: D. to create a path length difference
- A. one slit is for frequency, the other for wavelength
- B. wo slits in parallel offer less resistance
- C. to increase the intensity
- D. to create a path length difference
Explanation
In Young's double-slit experiment, the presence of two slits allows for the creation of a path length difference between the light waves passing through the two slits. This path length difference is essential for the formation of interference patterns.

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.
