When an unpolarized light of intensity $I_0$ is incident on a polarizing sheet, the intensity of the light which does not get transmitted is
A thin glass (refractive index 1.5) lens has optical power of $-5 D$ in air. Its optical power in a liquid medium with refractive index $1.6$ will be
If $\mathrm{I}_0$ is the intensity of the principal maximum in the single slit diffraction pattern, then what will be its intensity when the slit width is doubled?
A Young’s double slit experiment uses a monochromatic source. The shape of the interference fringes formed on a screen is
Two point white dots are $1 \mathrm{~mm}$ apart on a black paper. They are viewed by eye of pupil diameter $3 \mathrm{~mm}$. Approximately, what is the maximum distance at which these dots can be resolved by the eye? [ Take wavelength of light $=500 \mathrm{~nm}$ ]
A fish looking up through the water sees the outside world contained in a circular horizon. If the refractive index of water is $4 / 3$ and the fish is $12 \mathrm{~cm}$ below the surface, the radius of this circle in $\mathrm{cm}$ is
