Consider the following statement \(A\) and \(B\) and identify the correct answer.
1 A and B are true
2 A and B are false
3 \(\mathrm{A}\) is true but \(\mathrm{B}\) is false
4 \(\mathrm{A}\) is false but \(\mathrm{B}\) is true
Explanation:
: Fresnel's diffraction pattern, source and screen are of finite distance. Polarization is used to estimate the helical structure of nucleic acid

In Fraunhofer diffraction experiment, \(L\) is the distance between screen and the obstacle, \(b\) is the size of obstacle and \(\lambda\) is wavelength of incident light. The general condition for the applicability of Fraunhofer diffraction is
: The general condition for fraunhofer diffraction is, \(\frac{\mathrm{b}^2}{\mathrm{~L} \lambda}<<1 \text {. }\)

Fraunhofer lines are due to
1 absorption by chromospheres of the light emitted by photosphere
2 absorption by photospheres of the light emitted by chromospheres
3 light emitted by photosphere
4 light emitted by chromospheres
Explanation:
: Fraunhofer lines are due to absorption by chromospheres of the light emitted by photosphere. This leads to dark lines in the spectrum called Fraunhofer lines.
