Q.38 Four independent waves are expressed as:
(i) y1 = a1 sin ωt (ii) y2 = a2 sin 2ωt
(iii) y3 = a3 cos ωt (iv) y4 = a4 sin (ωt + π/3)
The interference is possible between:
(1) (i) and (ii) (2) (i) and (iv)
(3) (iii) and (iv) (4) Not possible at all
Q.39 Interference proves:
(1) transverse nature of a wave
(2) longitudinal nature of a wave
(3) wave-nature
(4) particle-nature
Q.40 In Young's double slit interference experimebnt if
the distance between the slits is made 3-fold, the
fringe width becomes:
(1) (1/3)-fold (2) 3-fold
(3) (1/9)-fold (4) 9-fold
Q.41 As intensity of incident light increases
(1) photoelectric current increase
(2) K.E. of emitted photoelectron increases
(3) photo electric current decreases
(4) K.E. of emitted photoelectrons decreases
Q.42 According to Einstein's photoelectric equation, the
plot of the kinetic energy of the emitted photo
electrons from a metal Vs the frequency of the
incident radiation gives an straight line whose slope
(1) depends both on the intensity of the radiation
and the metal used
(2) depends on the intensity of the radiation
(3) depends on the nature of the metal used
(4) is the same for the all metals and independent of
the intensity of the radiation
