What is the point called where light rays meet after passing through a convex lens?

• Divergence point

• Focal point

• Refraction point

• Convergence point

How do light rays behave when passing through a concave lens?

• They converge at a point

• They diverge away from each other

• They remain parallel

• They stop

What type of image is formed by a concave lens?

• Real and upright

• Virtual and upright

• Virtual and inverted

• Real and inverted

What determines the size of the image formed by a lens?

• The color of the lens

• The shape of the lens

• The focal length and distance between the lens and the object

• The temperature of the lens

What is the focal length of a lens?

• Distance from the center of the lens to the focal point

• Distance from the lens to the image

• Distance from the lens to the light source

• Distance from the lens to the object

Can the focal length of a lens affect the size of the image?

• Yes, along with the distance between the lens and the object

• No, it has no effect

• Yes, but only in concave lenses

• Yes, but only in convex lenses
