Q
Q: An object is placed 30 cm from a concave lens of focal length 15 cm. What is the nature of the image formed?
Solution:
For a concave lens, the image formed is virtual and erect when the object is placed in front of it.
Steps: 5
Show Steps
Step 1: Identify the type of lens. In this case, it is a concave lens.
Step 2: Note the distance of the object from the lens, which is 30 cm.
Step 3: Understand the focal length of the lens, which is -15 cm (concave lenses have a negative focal length).
Step 4: Recall that for a concave lens, the image formed is always virtual and erect when the object is placed in front of it.
Step 5: Conclude that since the object is in front of the concave lens, the image will be virtual and erect.
