The ratio of resolving powers of an optical microscope for two wavelengths ${\lambda }_1=4000\text{A˚}$ and ${\lambda }_2=6000\text{A˚}$ is:

A thin prism having refracting angle $10^{\circ }$ is made of glass of refractive index $1.42$. This prism is combined with another thin prism of glass of refractive index $1.7$. This combination produces dispersion without deviation. The refracting angle of the second prism should be:

A capacitor is charged by a battery. The battery is removed and another identical uncharged capacitor is connected in parallel. The total electrostatic energy of the resulting system:

Preeti reached the metro station and found that the escalator was not working. She walked up the stationary escalator in time $t_1$. On other days, if she remains stationary on the moving escalator, then the escalator takes her up in time $t_2$. The time taken by her to walk up on the moving escalator will be:

Match the following thermodynamic processes with their $P-V$ diagram characteristics:
