In a Young's double slit experiment for a particular wavelength of light the distance between third dark and fifth bright fringe is 1.63 mm . If the distance between two slit is 1 mm and distance between slit and screen is 1 metre. Then, th...

A beam of light travelling in water strikes a glass plate which is also immersed in water. When the angle of incidence is $60^{\circ}$, the reflected beam is found to be plane polarised. Find the refractive index of glass, if refractive ind...

Young's double slit experiment is performed in a medium of refractive index of 1.33 . The maximum intensity is $ I_{0} $. The intensity at a point on the screen, where path difference between the light coming out from slits is $ \frac{\lamb...

In YDSE, monochromatic light falls on a screen 1.80 m from two slits separated by 2.08 mm . The first and second order bright fringes are separated by 0.553 mm . The wavelength of light used is

In a YDSE, the light of wavelength \(\lambda=5000\mathop A\limits^o\) is used, which emerges in phase from two slits at \(a\) distance \(d=3 \times 10^{-7} \mathrm{~m}\) apart. A transparent sheet of thickness $$t=1.5 \times 10^{-7} \mathr...

In a young's double slit arrangement fringes are produced using light of wavelength 4000 \(\mathop A\limits^o\). One slit is covered by a thin plate of glass of refractive index 1.4 and the other with another glass plate of same thickness ...
