List of top Physics Questions on Wave optics asked in BCECE

Young's double slit experiment is first performed in air and then in a medium other than air. It is found that the 9th bright fringe in the medium lies where the 5th dark fringe lies in the air, then the refractive index of the medium is:

The resolving power of a telescope is directly proportional to:

The velocity of light in a medium is √3\(\times\)10⁸m/s. The polarizing angle of incidence is:

Angular width of central maxima in the Fraunhofer's diffraction pattern is measured. Slit is illuminated by the light of wavelength 6000 $\mathring {A}$. If slit is illuminated by light of another wavelength, angular width decreases by 30%. Wavelength of light used is
