In case of linearly polarised light, the magnitude of the electric field vector:

The circuit shown below acts as:

For ensuring dissipation of same energy in all three resistors ($R_1,R_2,R_3$) connected as shown in figure, their values must be related as:

The apparent depth of water in cylindrical water tank of diameter $2R\text{cm}$ is reducing at the rate of $x\text{cm/minute}$ when water is being drained out at a constant rate. The amount of water drained in $\text{c.c.}$ per minute is ($n_1=\text{refractive index of air}$, $n_2=\text{refractive index of water}$):

A candle of diameter $d$ is floating on a liquid in a cylindrical container of diameter $D(D>>d)$ as shown in figure. If it is burning at the rate of $2\text{cm/hour}$ then the top of the candle will:
