List of top Physics Questions on wave interference asked in COMEDK UGET

If the intensity of the central maximum in the Young's double slit experiment is $I_0$, what will be the intensity at the same region when one of the slits is blocked by an opaque object?

The width of the fringes obtained with light of wavelength $2 \times 10^{-7}\text{ m}$ is $82\text{ mm}$. If the entire apparatus is immersed in a liquid of refractive index $3$, what will be the width of the resulting fringes?

The interference pattern is obtained with two coherent light sources of intensity ratio \( 9 : 1 \). The ratio of \( \frac{I_{MAX}+I_{MIN}}{I_{MAX}-I_{MIN}} \) is \( \frac{\alpha}{\beta} \). The values of \( \alpha \) and \( \beta \) are:

In the Young's double slit experiment, when a monochromatic light is used, fringe width obtained is 1 mm. If the wavelength is halved and the slit width is doubled, what will be the new fringe width?
