To determine the position of a point object precisely_______light should be used.

A plane polarised light is incident normally on a tourmaline plate. Its $\overrightarrow{\mathrm{E}}$ vector makes an angle of $60°$with the optic axis of the plate. Find the % difference between the initial and final maximum values of the $\overrightarrow{\mathrm{E}}$ vector.

With proper diagram, explain the resolving power of a microscope and obtain its formula.

The distance between two slits in Young's experiment is $0.2 \mathrm{mm}$. If the wavelength of light is $5000 \stackrel{\circ }{\mathrm{A}}$, the angular position of $3^{\mathrm{rd}}$ bright fringe from the central bright fringe is ______ rad.

To determine the position of a point like object precisely, _____ light should be used.

State and prove Brewster's law.

The intensity of diffracted light at any point on the screen is given by the formula $I=I_o{\left(\frac{\sin \alpha }{\alpha }\right)}^2$, using this formula give the conditions for central maximum, minima, and maxima. Where $I_{\circ }=$maximum intensity and $\alpha =\frac{\mathrm{\pi d} \mathrm{sin\theta }}{\lambda }$.

In young's experiment, the distance between two slits and that between plates and the screen are $0.05 \mathrm{cm}$ and $1 \mathrm{m}$, respectively. Find the distance between third bright and fifth dark fringes. Take the wavelength of the light equal to $5000 \stackrel{\circ }{\mathrm{A}}$.
