Light Reflection and Vision

What is reflection of light?

• The absorption of light by an object when it strikes its surface.

• The emission of light by an object when it is struck by another light source.

• The bending of light as it passes through a medium.

• The bouncing back of light when it strikes the surface of an object and does not pass through it.

What is the law of reflection?

• The angle of incidence is not related to the angle of reflection.

• The angle of incidence is equal to the angle of reflection.

• The angle of incidence is less than the angle of reflection.

• The angle of incidence is greater than the angle of reflection.

What are the two types of mirrors?

• concave mirrors and convex mirrors

• magnifying mirrors

• plane mirrors

• funhouse mirrors

What is the difference between concave and convex mirrors?

• Concave mirrors are curved inward and can form both real and virtual images, while convex mirrors are curved outward and can only form virtual images.

• Concave mirrors are curved outward and can form both real and virtual images, while convex mirrors are curved inward and can only form virtual images.

• Concave mirrors are flat and can only form virtual images, while convex mirrors are curved outward and can form both real and virtual images.

• Concave mirrors are curved inward and can only form virtual images, while convex mirrors are curved outward and can form both real and virtual images.

What is a lens?

• A lens is a transparent optical device that focuses or disperses light to form an image.

• A lens is used to measure distance.

• A lens is a curved piece of glass.

• A lens is a type of camera.

What are the two types of lenses?

• meniscus and cylindrical

• convex and concave

• biconvex and biconcave

• plano-convex and plano-concave

What is the difference between concave and convex lenses?

• Convex lenses are thinner at the center and thicker at the edges.

• Concave lenses are thicker at the center and thinner at the edges.

• Concave lenses are used for magnification, while convex lenses are used for reducing image size.

• Concave lenses are thinner at the center and thicker at the edges, while convex lenses are thicker at the center and thinner at the edges.
