Question: An object is placed 10 cm from a convex lens with a focal length of 5 cm. What is the nature of the image formed? (2022)

Options:

Correct Answer: Virtual and erect

Exam Year: 2022

Solution:

Since the object distance is less than the focal length, the image formed is virtual and erect.

An object is placed 10 cm from a convex lens with a focal length of 5 cm. What is the nature of the image formed? (2022)

An object is placed 10 cm from a convex lens with a focal length of 5 cm. What is the nature of the image formed? (2022)

Step 1: Identify the type of lens. In this case, it is a convex lens.
Step 2: Note the focal length of the lens, which is given as 5 cm.
Step 3: Identify the object distance, which is given as 10 cm.
Step 4: Compare the object distance (10 cm) with the focal length (5 cm).
Step 5: Since the object distance (10 cm) is greater than the focal length (5 cm), we need to check the image characteristics.
Step 6: For a convex lens, if the object is placed beyond the focal length, the image is real and inverted. However, if the object is placed within the focal length, the image is virtual and erect.
Step 7: Since the object distance (10 cm) is greater than the focal length (5 cm), we conclude that the image formed is virtual and erect.

Lens Formula – Understanding the relationship between object distance, image distance, and focal length in lens systems.
Image Characteristics – Determining the nature (real or virtual) and orientation (erect or inverted) of the image formed by a lens.
