Convex and Concave Lens

What is the focal point of a concave lens?

• The point where light rays converge after passing through the lens

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

• The point where light rays reflect off the lens

• The point where light rays pass through the lens without bending

What type of image is formed by a concave lens?

• A real image

• A virtual image

• An inverted image

• A magnified image

What is the distance from the center of the lens to the focal point called?

• Focal length

• Refraction distance

• Convergence point

• Incident ray

How does the focal length of a lens affect the size of the image?

• A longer focal length will make the image smaller

• A longer focal length will make the image larger

• A shorter focal length will make the image smaller

• A shorter focal length will make the image larger

What causes light rays to refract when passing through a lens?

• The thickness of the lens

• The curvature of the lens

• The speed of the light rays

• The color of the light
