In Young’s double slit experiment, if the separation between the slits is halved, and the distance between the slits and the screen is doubled, then the fringe width compared to the unchanged one will be
In Young’s double slit experiment, if the separation between the slits is halved, and the distance between the slits and the screen is doubled, then the fringe width compared to the unchanged one will be
Show Hint
Fringe width $\propto \frac{D}{d}$, so increasing $D$ and decreasing $d$ increases spacing.

Top Questions on wave interference
- Assertion (A): When two waves of equal amplitude and a phase difference of \( \frac{\pi}{2} \) interfere, the resulting intensity is equal to the intensity of one wave. Reason (R): In interference, the resultant intensity is always the sum of individual intensities if the phase difference is non-zero.

- The Young's double slit interference experiment is performed using light consisting of 480 nm and 600 nm wavelengths to form interference patterns. The least number of the bright fringes of 480 nm light that are required for the first coincidence with the bright fringes formed by 600 nm light is:

- A thin transparent film with refractive index 1.4 is held on a circular ring of radius 1.8 cm. The fluid in the film evaporates such that transmission through the film at wavelength 560 nm goes to a minimum every 12 seconds. Assuming that the film is flat on its two sides, the rate of evaporation is:
