Wave Nature and Polarization – Rankers Physics

Miscellaneous: Practice Problem & Solution

Assertion (A): Wave nature can be proved by phenomena of interference and diffraction. Reason (R): Only transverse wave can show the phenomena of polarization.
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Solution Explained:

To solve this problem, we apply the core principles of Miscellaneous. Understanding the underlying formula is key to arriving at the correct answer below:

Assertion (A) is true. Interference and diffraction are characteristic wave phenomena, providing strong evidence for the wave nature of light.

Reason (R) is true. Polarization is a property exclusive to transverse waves, where oscillations are perpendicular to the propagation direction.
Reason (R) describes a unique property of transverse waves, which is distinct from demonstrating wave nature via interference/diffraction. Thus, (R) does not explain (A).

1. A parallel beam of monochromatic light of wavelength $5000 \AA$ is incident normally on a single narrow slit of width 0.001 mm. The light is focused by a convex lens on a screen placed in focal plane. The first minimum will be formed for the angle of diffraction equal to (1993)
2. Assertion (A): We cannot get diffraction pattern from a wide slit illuminated by monochromatic light. Reason (R): In diffraction pattern, all the bright bands are not of the same intensity.  
3. Assertion (A): If in YDSE, wavelength of light used is increased, angular width remain unchanged only linear width of fringes increases. Reason (R): Only linear fringe width proportional to wavelength and angular fringe width does not depends on wavelength.  
4. Assertion (A): As angle subtended by the diameter of objective lens at the focus of microscope increased, resolving limit also increases. Reason (R): Resolving limit proportional to tangent of the angle subtended by the diameter of objective lens at the focus of microscope.  
5. For a parallel beam of monochromatic light of wavelength '$\lambda$', diffraction is produced by a single slit whose width 'a' is of the order of the wavelength of the light. If 'D' is the distance of the screen from the slit, the width of the central maxima will be: (2015)
