The positions of bright fringes in young's double slit experiment are given by
Correct answer: A. y = m λ L / d
- A. y = m λ L / d
- B. y = m d L
- C. y = m L d / λ
- D. y = m d / L
Explanation
The correct formula for the positions of bright fringes in Young's double-slit experiment is y = m λ L / d. Here, 'y' represents the fringe position, 'm' is the fringe order (an integer), 'λ' is the wavelength of light used, 'L' is the distance from the slits to the screen, and 'd' is the separation between the two slits. This formula is derived from the condition for constructive interference. The other options are incorrect due to missing or misplaced components of the formula.

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.
