A camera employs a ___ lens to form ___ images

In concave lenses, a distant object appears

Angle between incident ray and normal is known as

A human eye employs a ___ lens to form ____images

Concave lens is also known as

the focal length of a diverging lens is

the ratio of the speed of light in a vacuum to the speed of light is a material known as

an object is located 2cm in front of a flat mirror. the image formed in the mirror is

green laser light (500nm) passes into liquid with n=2 what is the new wave length

as light passes from less dense medium into more dense medium, it will bend towards the normal. If the light ray passes from more dense to less dense, it bends away from the normal. This is known as

a convex lens in which light rays that enter it parallel to its axis converge at a single point on the opposite side is known as

for a converging lens or mirror, the point at which converging light rays cross; for a diverging lens or mirror, the point from which diverging light rays appear to originate

an object consisting of two mutually perpendicular reflecting surfaces, so that the light that enters is reflected back exactly parallel to the direction from which it came

a concave mirror in which light rays that strike it parallel to its axis converge at one or more points along the axis is known as
