Most Important MCQs For Up Bsc Nursing CNET KGMU ABVMU
Q.1 Two plane monochromatic waves propagating in the same direction with amplitudes A and 2 A and differing fin phase by 𝚷 / 3 rad superpose. Calculate the amplitude of the resultant wave..
Q.2 In Young’s double experiment, the two parallel slits are made one millimetre apart and a screen is placed one metre away. What is the fringe separation when blue green light of wavelength 500 nm is used?
Q.3 Laser light of wavelength 630 nm incident on a pair of slits produces an interference pattern in which the bright fringes are separated by 8.1 mm. A second light produces an interference pattern in which the fringes are separated by 7.2 mm. Calculate the wavelength of the second light.
Q.4 Yellow light of wavelength 6000 Å produces fringes of width 0.8 mm in Young’s double slit experiment. What will be the fringe width if the light source is replaced by another monochromatic source of wavelength 7500 Å and the separation between the slits is doubled ?
Q.5 What is the ratio of slit widths if the amplitudes of light waves from them have a ratio of √2 :1 ?
Q.6 Roughly calculate the limit of resolution of 100 cm telescope with visible light of wavelength λ =5500 A^0
Q.7 Calculate the resolving power of this telescope, assuming the diameter of the objective lens to be 6 cm and the wavelength of light used to be 540 nm.
Q.8 The objective of a telescope has a diameter of 125 cm. Calculate the smallest angular separation of two stars, measured in seconds, that may be resolved by it. Mean wavelength of light = 6000 Å
Q.9 What is the aperture of the objective of a telescope that can be used to just resolve stars separated by 6 x 〖10〗^(-6)rad. Given lambda = 5.8 x 〖10〗^(-5)cm.
Q.10 Three identical polaroid sheets P₁, P₂ and P_3 are oriented so that the (pass) axes of P_2 and P_3 are inclined at angles of 60° and 90°, respectively, with respect to the (pass) axis of P₁ A monochromatic source, S, of intensity I_0 is kept in front of the polaroid sheet P₁ Find the intensity of the light, as observed by observers O₁, O₂ and O_3 positioned as shown below
