Image Formation by a Convex Lens

Question 1: What is the nature of image formed by a convex lens when the object is placed beyond the 2F point.

• Option B: No image formed

• Option A: Virtual and upright image

• Option C: Real and upright image

• Option A: Real and inverted image

Question 2: What happens to the rays when the object is placed at the focal point of a convex lens?

• They become parallel

• They spread out in all directions

• They converge at the focal point

• They disappear completely

Question 3: Explain the significance of the focal point in the image formation by a convex lens.

• The focal point is where parallel rays of light converge after passing through the lens.

• The focal point is where the light rays diverge after passing through the lens.

• The focal point has no significance in image formation by a convex lens.

• The focal point is where the lens absorbs all the light rays.

Question 4: What is the role of the principal axis in determining the position of the image formed by a convex lens?

• It provides a reference line for measuring distances and angles.

• It helps in focusing the light rays onto the lens

• It determines the color of the image formed

• It has no role in determining the position of the image

Question 5: Describe the image formation by a convex lens when the object is placed at infinity.

• Real and upright point image at the center of the lens

• Virtual and upright point image at the focus of the lens

• Real and inverted point image at the focus of the lens

• Virtual and inverted point image at the center of the lens
