Question

Question 24 A converging lens creates an image of the object shown in the diagram. The object is further from the lens than the case (A) object focal point. In case (B), a region on one side of the lens airair is filled with water a) I you are in the water in case (B) case (B), where will the i mage appear to be from object your perspective (compared to case (A) closer to the lens, at the s air air water ame position, or furtherf rom the lens. (Assume your eyesight is perfect!) case (C) (b) Now consider the same converging lens, with an object closer than its object focal point. In case (D), a region on one side of the lens is filled with airair water. If you are in the water in case (D), where case (D) will the image appear to be from your perspective (compared to case (C)): closer to object the lens, at the same irair water position, or further fromt he lens. (Assume your eyesight is perfect!) Explain your answers and use ray diagrams with principle rays in each of your responses.

Answer 1

case (A) in air, a converging lens forms an inverted image Image case (B) water has higher refractive index than air so right rays will bend more towards focal point so image will be formed closer compared to case A water mae Image airar as Light rays bend more in water region, light rays will travel more to form image orn the other side so image will be farther. airair water
