Question: What happens to the image distance when the object distance is increased in a convex lens? (2022)

Options:

Correct Answer: Image distance increases

Exam Year: 2022

Solution:

As the object distance increases in a convex lens, the image distance also increases, moving further away from the lens.

What happens to the image distance when the object distance is increased in a convex lens? (2022)

Step 1: Understand what a convex lens is. A convex lens is thicker in the middle and can focus light rays that come through it.
Step 2: Identify the object distance. This is how far the object (like a candle or a light bulb) is from the lens.
Step 3: Recognize that when you move the object further away from the lens, you are increasing the object distance.
Step 4: Know that a convex lens creates an image of the object. The position of this image depends on the object distance.
Step 5: Realize that as you increase the object distance, the image distance (how far the image is from the lens) also increases.
Step 6: Conclude that moving the object further away from the lens causes the image to move further away from the lens as well.

Lens Formula – The relationship between object distance, image distance, and focal length in a convex lens, typically expressed as 1/f = 1/v + 1/u.
Image Formation – Understanding how the position of the object affects the position of the image formed by a convex lens.
