Curved Surfaces and Light Reflection

What type of mirror is curved inward?

• Concave mirror

• Reflective mirror

• Flat mirror

• Convex mirror

How does a concave mirror affect light rays?

• A concave mirror diverges light rays away from a focal point.

• A concave mirror reflects light rays without changing their direction.

• A concave mirror converges light rays to a focal point.

• A concave mirror absorbs light rays instead of reflecting them.

What is the focal point of a concave mirror?

• The focal point is the point where light rays are absorbed.

• The focal point is where light rays diverge.

• The focal point is the point where parallel light rays converge after reflection.

• The focal point is the center of the mirror.

What type of mirror is curved outward?

• Plane mirror

• Concave mirror

• Flat mirror

• Convex mirror

How do convex mirrors affect the size of images?

• Convex mirrors produce larger real images than the actual objects.

• Convex mirrors create images that are always inverted.

• Convex mirrors have no effect on the size of images.

• Convex mirrors produce smaller virtual images than the actual objects.

What is the main use of convex mirrors in vehicles?

• To increase the size of side mirrors.

• To enhance night vision for drivers.

• To provide a wider field of view and reduce blind spots.

• To improve fuel efficiency of the vehicle.

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

• Light rays diverge away from each other after passing through a convex lens.

• Light rays are absorbed completely by a convex lens.

• Light rays scatter randomly when passing through a convex lens.

• Light rays converge at a focal point when passing through a convex lens.

What is refraction?

• Refraction is the reflection of light off a surface.

• Refraction is the scattering of light in different directions.

• Refraction is the absorption of light in a medium.

• Refraction is the bending of light as it passes from one medium to another.

How does the curvature of a lens affect refraction?

• The curvature of a lens affects refraction by determining the degree to which light rays are bent, influencing the lens's focusing power.

• The curvature of a lens has no effect on light refraction.

• Curvature of a lens only affects color, not refraction.

• Only the material of the lens affects refraction, not its curvature.

What is the difference between reflection and refraction?

• Reflection occurs only in water; refraction occurs in air.

• Reflection and refraction are the same phenomenon.

• Reflection is the bouncing of light; refraction is the bending of light.

• Reflection is the bending of light; refraction is the bouncing of light.
