1.	A concave mirror forms an image of the sun at a distance of 12 cm from it.A. the radius of curvature of this mirror is 6cmB. to use it as a shaving mirro, it can be held at a distance of 8-10cm from the faceC. it an object is kept at a distance of 24cm from it, the image formed will be of the same size as the objectD. all the above alternative are correct.
Answer» Correct Answer - b.,c. Image of sun will be formed at the focus of mirro. Hence, focal length of mirro `=12cm`. To use it or shaving purpose, face should be between focus and pole, so that virtual image can be formed.

A large transparent cube (refractive index = 1.5) has a small air bubble inside it. When a coin (diameter 2 cm) is placed symmetrically above the bubble on the top surface of the cube, the bubble cannot be seen by looking down into the cube at any angle. However, when a smaller coin (diameter 1.5 cm) is placed directly over it, the bubble can be seen by looking down into the cube. What is the range of the possible depths d of the air bubble beneath the top surface ?
