A transpar ent rod 40 cm long is cut flat at one end and rounded to a hemispherical surface 12 cm radius at the other end. A small object is embedded within the rod along its axis and half way between its ends. When viewed from the flat end of the rod, the object appears 10 cm deep. What is its apparent depth when viewed from the curved end?

To solve the problem, we need to determine the apparent depth of the object when viewed from the curved end of the rod. We will use the principles of optics, specifically the refraction of light. ### Step-by-Step Solution: 1. **Understanding the Setup**: - The rod is 40 cm long, with one end flat and the other end rounded into a hemispherical shape with a radius of 12 cm. - The object is located halfway along the rod, which means it is 20 cm from the flat end and 20 cm from the curved end. ...
