Lenses Lesson

What is a concave lens?

• A concave lens is a lens that is convex in shape.

• A concave lens is a lens that is thinner at the center and thicker at the edges.

• A concave lens is a lens that is thicker at the center and thinner at the edges.

• A concave lens is a lens that is the same thickness throughout.

What is the shape of a concave lens?

• Curved inward

• Spherical

• Flat

• Curved outward

What happens to light rays when they pass through a concave lens?

• The light rays converge or come together.

• The light rays remain parallel.

• The light rays bend towards the center of the lens.

• The light rays diverge or spread out.

What is a convex lens?

• A convex lens is a lens that is the same thickness throughout.

• A convex lens is a lens that is concave in shape.

• A convex lens is a lens that is thinner in the middle and thicker at the edges.

• A convex lens is a lens that is thicker in the middle and thinner at the edges.

What is the shape of a convex lens?

• Convex

• Spherical

• Cylindrical

• Concave

What happens to light rays when they pass through a convex lens?

• They converge at the focal point.

• They scatter in random directions.

• They remain parallel to each other.

• They diverge away from the focal point.

What are the properties of a concave lens?

• A concave lens forms a real, inverted and magnified image of the object placed in front of it.

• A concave lens converges the light rays that pass through it.

• A concave lens is thinner at the center and thicker at the edges. It diverges the light rays that pass through it and forms a virtual, erect and diminished image of the object placed in front of it.

• A concave lens is thicker at the center and thinner at the edges.

What are the properties of a convex lens?

• A convex lens has negative focal length and diverges light rays to form virtual, upright, and diminished images.

• A convex lens has positive focal length and converges light rays to form real, inverted, and magnified images.

• A convex lens has positive focal length and diverges light rays to form real, upright, and diminished images.

• A convex lens has zero focal length and does not affect the path of light rays.

How does a concave lens diverge light?

• A concave lens converges light by causing the light rays to bend towards the center of the lens.

• A concave lens does not affect the direction of light.

• A concave lens absorbs light instead of diverging it.

• A concave lens diverges light by causing the light rays to bend away from the center of the lens.

How does a convex lens converge light?

• A convex lens converges light by refracting it towards the center of the lens.

• A convex lens diverges light away from the center of the lens.

• A convex lens scatters light in all directions.

• A convex lens absorbs light and does not affect its direction.
