364919 A glass slab of thickness \(3\;cm\) and refractive index 1.5 is placed in front of a concave mirror. What is the radius of curvature of the mirror, so that the image coincides with the object?

364920 A rectangular tank of depth 8 meter is full of water \(\left( {\mu = 4{\rm{/}}3} \right)\) , the bottom is seen at the depth:

364921 A microscope is focused on an object at the bottom of a bucket. If liquid with refractive index \(5 / 3\) is poured inside the bucket, then microscope have to be raised by \(30\;cm\) to focus the object again. 'The height of the liquid in the bucket is

364922 An opaque cylindrical tank with an open top has a diameter of 3.00 \(m\) and is filled with water. When the setting sun reaches an angle of \({37^{\circ}}\) above the horizon, sunlight ceases to illuminate any part of the bottom of the tank. How deep is the tank ?
