JEE MainPhysicsGeometrical OpticsMCQ+4 / −1
A concave mirror has radius of curvature of 40 cm. It is at the bottom of a glass that has water filled up to 5 cm (see figure). If a small particle is floating on the surface of water, its image as seen, from directly above the glass, is at a distance d from the surface of water. The value of d is dose to: (Refractive index of water = 1.33) JEE Main 2019 (Online) 12th April Morning Slot Physics - Geometrical Optics Question 178 English
