Water rises to a height $h$ in a capillary tube. If the length of capillary tube above the surface of water is made less than $h$, then:

In an astronomical telescope in normal adjustment, a straight black line of the length $L$ is drawn on the objective lens. The eye-piece forms a real image of this line. The length of this image is $I$. The magnification of the telescope is:

The value of coefficient of volume expansion of glycerin is $5\times 10^{-4}{\text{K}}^{-1}$. The fractional change in the density of glycerin for a rise of $40^{\circ }\text{C}$ in its temperature is:

A photoelectric surface is illuminated successively by monochromatic light of wavelength $\lambda$ and $\frac{\lambda }{2}$. If the maximum kinetic energy of the emitted photoelectrons in the second case is $3$ times that in the first case, the work function of the surface of the material is:

A beam of light consisting of red, green and blue colours is incident on a right angled prism. The refractive index of the material of the prism for the above red, green and blue wavelengths are $1.39,1.44$ and $1.47$ respectively. The prism will:
