Sr. # Questions Answers Choice
1 Absolute temperature can be calculated by Mean square velocity Motion of the molecule Both (A) and (B) None of these
2 Which of the following is not thermo dynamical function? Enthalpy Work done Gibb's energy Internal energy
3 At constant volume temperature is increased then Collision on walls will be less Number of collisions per unit time will increase Collisions will be in straight lines Collisions will not change
4 The number of translation degrees of freedom for a diatomic gas is 2 3 5 6
5 Relation between pressure (P) and energy (E) of a gas is P = 2/3 E P = 1/3 E P = 3/2 E P = 3 E
6 Huygen's wave theory of light cannot explain Diffraction Interference Polarization Photoelectric effect
7 The contrast in the fringes in any interference pattern depends on Fringe width Intensity ratio of the sources Distance between the slits Wavelength
8 If yellow light emitted by sodium lamp in Young's double slit experiment is replaced by monochromatic blue light of the same intensity Fringe width will decrease Fringe width will increase The fringe width will remain unchanged Fringes will become less intense
9 Which one of the following phenomena is not explained by Huygen's construction of wavefront? Refraction Reflection Diffraction Origin of spectra
10 Light appears to travel in straight lines since It is not absorbed by the atmosphere It is reflected by the atmosphere Its wavelength is very small Its velocity is very large
11 The twinkling of stars is due to The fact that stars do not emit light continuously The refractive index of the earth's atmosphere fluctuate Intermittent absorption of star light by its own atmosphere None of them
12 A prism splits a beam of white light into its seven constituent colors this is so because Phase of different colors is different Amplitude of different colors is different Energy of different colors is different Velocity of different colors is different
13 A sun rise or sun set, the sun looks reddish because. The sun is coldest at these times Of the effects of reflection and refraction The sun is hottest at these times Of the scattering of light
14 One cannot see through fog because Fog absorbs light The refractive index of fog is infinity Light suffers total reflection at the droplet in a fog Light is scattered by the droplets in fog
15 The distance between node and anti-node is λ λ/2 λ/4 2λ
