(C) In Young's double-slit experiment, the path difference at the central point is zero for all wavelengths $(\Delta x = 0)$.Since $\Delta x = 0$ for all wavelengths, all colours overlap at the central point, resulting in a central white fringe.For other fringes, the position of the $n^{th}$ bright fringe is given by $y_n = \frac{n \lambda D}{d}$.Since $\lambda_{violet} Therefore, the correct statement is that there is a central white fringe, and the violet fringes are closer to it than the red fringes.

Young's Double Slit Experiment (YDSE)

In a Young's double-slit experiment,the light beam consists of two wavelengths $6500 \, \mathring{A}$ and $5200 \, \mathring{A}$. The distance between the slits is $2 \, mm$ and the distance between the plane of the slits and the screen is $120 \, cm$. What is the minimum distance from the central maximum where the bright fringes of both wavelengths coincide (in $, cm$)?

Difficult

View Solution

In a Young's double-slit experiment,the fringe pattern is observed on a screen placed at a distance $D$. The slits are separated by $d$ and are illuminated by light of wavelength $\lambda$. Find the distance from the central point where the intensity falls to half the maximum intensity.

Difficult

View Solution

In Young's double-slit experiment,the position of the $5^{\text{th}}$ bright fringe from the central maximum is $5\,cm$. The distance between the slits and the screen is $1\,m$ and the wavelength of the monochromatic light used is $600\,nm$. The separation between the slits is $........\mu m$.
