Assertion: In a movie, ordinarily 24 frames are projected per second from one end to the other of the complete film.
Reason: The image formed on retina of eye is sustained upto \(1 / 10\) second after the removal of stimulus.
1 If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
2 If both Assertion and Reason are correct but Reason in not a correct explanation of the Assertion.
3 If the Assertion is correct but Reason is incorrect.
4 If both the Assertion and Reason are incorrect.
(e) If the Assertion is incorrect but the Reason is correct.
Explanation:
C: The image formed on ratina of eye is sustained up to \(1 / 16^{\text {th }}\) second after removal of 16 of stimulus. So, no. of frames should be 16 per second.

The resolving power of a microscope can be increased by selecting an appropriate medium between the object and the objective lens. For a fixed wavelength of light the resolving of a microscope can be increased with.
1 A medium with high density
2 A medium with high refractive index.
3 A medium with low refractive index.
4 A medium with high viscosity.
Explanation:
B: If refractive index \((\mu)\) of the medium between object and objective lens increases, the resolving power increases.
Resolving power \(=\mu \times\) Numerical aperture.

The resolving power of a microscope can be increased by
1 Increasing diameter of objective lens
2 Increasing diameter of eye lens
3 Increasing wavelength of light used
4 Decreasing wavelength of light used
Explanation:
D: Resolving power of telescope \((\mathrm{R})=\frac{\mathrm{a}}{1.22 \lambda}\)
Where, \(\lambda=\) Wavelength of light used
\(\mathrm{R} \propto \frac{1}{\lambda}\)
So, the resolving power of a microscope can be increased by decreasing wavelength of light used.
