Answer: d)
Explanation: Pure Silver is the best conductor of electricity, but since it is not so easily available, other alternatives are more popular. Electrical conductivity of a material is a function of how easily its atoms can provide free electrons to pass a current. Any material which does not have free electrons in its atoms, cannot conduct electricity.
9. Small liquid drops are spherical in shape because
a) of adhesion
b) of gravitational force
c) of the atmospheric pressure from all the sides on the top
d) the liquid tends to have the minimum surface area are due to surface tension
Answer: d)
Explanation: The liquid tends to have the minimum surface area are due to surface tension
A drop of a liquid tries to occupy the minimum surface are in a given volume as it is constantly under a kind of stretch among its molecules. This minimum area is achieved by assuming a spherical shape. These cohesive forces create surface tension which means that the upper surface of a liquid always shows tension.
10. The Chandershekhar Limit is related to which of the following?
a) Stars
b) Black holes
c) Both of these
d) None of these
Answer: a)
Explanation: It refers to the mass limit of the stars, beyond which they collapse. The Chandrasekhar limit is the maximum mass of a stable, white dwarf star. It is the mass above which electron degeneracy pressure in the star is not enough to its own gravitational pull. Consequently, white dwarfs with masses greater than this limit would suffer gravitational collapse, evolving into a neutron star or black hole.

Answer: a)
Explanation: In optics, refraction is a phenomenon that often occurs when waves travel from a medium with a given refractive index to a medium with another at an oblique angle. Reflection of light is either specular (mirror-like) or diffuse (retaining the energy, but losing the image) depending on the nature of the interface. Dispersion is the separation of white light into colours or of any radiation according to wavelength. Diffraction is the slight bending of light as it passes around the edge of an object.

23. Given below are two statements, one labelled as Assertion (A) and other labelled as Reason (R)
Assertion (A): A diamond sparkles more than a glass imitation cut to the same shape.
Reason (R): The refractive index of diamond is less than that of glass.
In context of the above two statements, which one of the following is correct ?
(a) Both A and R are true and R is the correct explanation of A
(b) Both A and R are true and R is not a correct explanation of A
(c) A is true but R is false
(d) A is false but R is true
Answer: c)
Explanation: The refractive index of diamond is very high (approximately 2.47) while the refractive index for the glass is 1.57. Therefore, the initial angle for the ray of light traveling form diamond to air is very low about 24°. The initial angle for the ray of light traveling from glass to air is 39°. Moreover the diamonds are usually cut with their faces in such a manner that once a ray of light enters into it, it suffers a large number of total internal reflections at various faces till the angle of incidence inside the diamond remains greater than the critical angle. In total internal reflection 100% of the light reflected back into the same medium. Hence, the object shines. That's why a diamond sparkles more than a glass imitation cut to the same shape.
24. An air bubble in water will act like a:
(a) convex mirror
(b) convex lens
(c) concave mirror
(d) cancave lens
Answer: d)
Explanation: Correct answer is Concave Lens
25. When a mirror is rotated by an angle 0, the reflected ray will rotate by:
(a) 0°
(b) 0/2
(c) 0
(d) 20
Answer: d)
Explanation: For given incident ray, if a plane mirror is rotated through a certain angle, then the reflected ray rotates through twice of that angle . So if a mirror is rotated by an angle 0, the reflected ray will rotate by 20.
