The speed of light in the material of a plano convex lens is 2 × 108 m/s and its greatest thickness Inside a solid glass sphere of radius R a point source of light lies at a distance x ( x VO if |u| > |F|ġ0. Surface intersect on x axis is (Neglect the ray which travels along x-axis as shown in figure) The width of the regionĪt which the incident rays after normal incidence on plane surface and subsequent refraction at curved Of a quarter cylinder, of radius R = 5 cm, and has the index of refraction n = 5/3. A uniform, horizontal parallel beam of light is incident upon a prism as shown. Each question has choices (A), (B), (C) and (D), out ofġ. This section contains 30 Single choice questions. In all other cases, minus one (–1) Mark will be awarded. For each question, you will be awarded 3 Marks if you give the correct answer and zero Mark if no answer Each question has 4 choices (A), (B), (C) and (D), out of which only one is correct.ģ. This Question Paper contains 30 objective type questions.Ģ. Then the direction of revolution (as seen from A) of the image of the particle and its speed is The radius of curvature of the mirror is 20 cm. The axis of the circle and the principal axis of the mirror M coincide. In the figure shown find the total magnification after two successive reflections first on M1 & then on M2ġ4.Ě particle revolves in clockwise direction (as seen from point A) in a circle C of radius 1 cm and completes one revolution in 2 sec. (D) a real, inverted, same sized image can be formed using a convex mirror.ġ3. (C) a virtual, erect, magnified image can be formed using a concave mirror (B) a virtual, erect, same sized image can be obtained by using a plane mirror (A) the magnification produced by a convex mirror is always less than one (except at the pole) How many mistakes are there in the ray diagram (AB is itsġ2.ğor a real object, all of the following statements are correct except : An object O is placed in front of this mirror. In the figure shown a convex mirror of radius of curvature 20 cm is shown. When light passes through them, the two slabs have the same number of waves. 1.5 and the other is made of materials B and C, the ratio of their thickness being 1: 2. Two transparent slabs are of equal length (thickness). The maximum angle of incidence for rays incident on the spherical glass- air interface directly from the point source is:ģ. The solid sphere is surrounded by air of refractive index 1. Inside a solid glass sphere of radius R a point source of light lies at a distance x ( x < R) from centre of the sphere. The width of the region at which the incident rays after normal incidence on plane surface and subsequent refraction at curved surface intersect on x axis is (Neglect the ray which travels along x-axis as shown in figure) The prism is in the shape of a quarter cylinder, of radius R = 5 cm, and has the index of refraction n = 5/3. Each question has choices (A), (B), (C) and (D), out of which ONLY ONE is correct.ġ.Ě uniform, horizontal parallel beam of light is incident upon a prism as shown.
