Q29.Light from a point source in air falls on a convex curved surface of radius 20 cm and refractive index 1 . 5. If the source is located at 100 cm from the convex surface, the image will be formed at ______ cm from the object. JEE Main 2024 (31 Jan Shift 2) JEE Main Previous Year Paper
What This Question Tests
This question applies the formula for refraction at a single spherical surface to find the image position and then calculates the distance of the image from the object.
Concepts Tested
