Geometrical Optics question

2021 · 17 Mar · Shift 2 · Q63

JEE MainPhysicsGeometrical OpticsNumerical+4 / −1
The image of an object placed in air formed by a convex refracting surface is at a distance of 10 m behind the surface. The image is real and is at 2rd3{{{2^{rd}}} \over 3}32rd​ of the distance of the object from the surface. The wavelength of light inside the surface is 23{2 \over 3}32​ times the wavelength in air. The radius of the curved surface is x13{x \over {13}}13x​ m. The value of 'x' is ‾\underline{\hspace{2cm}}​.
