The tip of a needle does not give a sharp image on a screen. This is due to
1 Polarisation
2 Interference
3 Diffraction
4 None of these
Explanation:
: The lights bend at the tip of the needle which is responsible for the formation of blurred image. This phenomenon is called diffraction. It occurs mainly at sharp edges like of needle.

An un-polarized beam of light is incident on a plane surface separating air and glass at an angle equal to the Brewster angle. Then
1 the reflected light has electric component only perpendicular to the incident plane
2 the reflected light has electric component only in the plane of incidence
3 the electric component parallel to the plane of incidence in refracted ray completely disappear
4 the magnetic component of the refracted light completely disappear
Explanation:
: When an unpolarised beam of light is incident on a plane surface separating air and glass at the Brewster's angle, only part of light with electric field vector perpendicular to the plane of incidence will be reflected.

Colours of thin soap bubbles are due to
1 refraction
2 dispersion
3 interference
4 diffraction
Explanation:
: The colours seen in a soap bubble arise from interference of light reflecting off the front and back surfaces of the thin soap film. Depending on thickness of film, different colours interfere constructively \& destructively.

Consider the following statements \(A\) and \(B\). Identify the correct answers:
1 A and B are correct
2 \(\mathrm{A}\) and \(\mathrm{B}\) are wrong
3 \(\mathrm{A}\) is correct and \(\mathrm{B}\) is wrong
4 A is wrong and B is Correct
Explanation:
: Nucleic acid is an optically active medium when circularly polariszed light passes through an absorbing optically active medium, the speeds b/w right and left polarizations differ as well as their wavelength this can be used to study the helical structure of nucleic acid. An optical axis is a line along which there is some degree of rotational symmetry in an optical system thus it is a particular direct and not any random line.

1 Both A and B are correct
2 Both \(\mathrm{A}\) and \(\mathrm{B}\) are wrong
3 A is correct B is Wrong
4 A is wrong B is correct
Explanation:
: When light passes through two axis mutually perpendicular the light is completely extinguished when a large strain is applied on the molecules they get oriented in the direction of strain and material becomes double refractive.
