Q: A diverging lens has a focal length of -15 cm. What is the nature of the image formed when an object is placed at 10 cm from the lens? (2023)

Solution: A diverging lens always forms a virtual and upright image when the object is placed in front of it.

Steps: 5

Step 1: Identify the type of lens. The lens is a diverging lens.
Step 2: Note the focal length of the lens. The focal length is -15 cm (negative indicates it's a diverging lens).
Step 3: Determine the position of the object. The object is placed at 10 cm from the lens.
Step 4: Understand how a diverging lens works. A diverging lens always forms a virtual image when the object is in front of it.
Step 5: Conclude the nature of the image. Since the object is in front of the lens, the image formed is virtual and upright.
