List of top Physics Questions on Wave optics asked in GUJCET

In a Young's double slit experiment, the slits are separated by 0.2 mm and placed 2.0 m away. The distance between the central bright fringe and the first bright fringe (fringe width) is measured to be 1.5 cm. Determine the wavelength of light used in the experiment.
According to Huygens principle the phase difference between oscillations of any two particles on a same wave front is ______ rad.
In a double-slit experiment, the distance between the slits is 0.54 mm and the distance from the screen is 1.8m. If the distance between the adjacent maxima is 1.2 cm, then the wavelength of the light used in the experiment is:
If the speed of light in a medium is \( 200 \times 10^8 \, \text{cm/s} \), calculate the refractive index for this medium given that \( c = 3 \times 10^{10} \, \text{m/s} \).
In the diffraction experiment, the angle of diffraction for the first order is \( \theta \). The corresponding wavelength of light is:
