List of top Physics Questions on wave interference asked in NEET (UG)

Two coherent sources of light interfere and produce fringe pattern on a screen. For central maximum, the phase difference between the two waves will be

In a double slit experiment, when light of wavelength \(400 nm\) was used, the angular width of the first minima formed on a screen placed \(1 m\) away, was found to be \(0.2°\). What will be the angular width of the first minima, if the entire experimental apparatus is immersed in water? \((\mu_{water}\)\(=\frac43)\) 

The interference pattern is obtained with two coherent light sources of intensity ratio n. In the interference pattern, the ratio $\frac{I_{max} - I_{min}}{I_{max} + I_{min}}$ will be

The phase difference between two waves, represented by $y_1=10^{-6} \sin[100t +(x/50)+0.5]\,m$ $y_2=10^{-6} \cos[100t +(x/50)]\,m$ where $x$ is expressed in metres and $t$ is expressed in seconds, is approximately.

Interference was observed in interference chamber where air was present, now the chamber is evacuated, and if the same light is used, a careful observer will see
