OPTICS

The branch of physics that deals with light and vision is called

• Prisms

• Optics

• Wavelength

Which type of lens is thick in the middle, is used to correct farsightedness, and refracts the light causing the image to be pulled in forward to the retina?

• convex lens

• concave lens

Which type of lens is thin in the middle, is used to correct nearsightedness, and spreads out the light which pushes the image back to the retina?

• convex lens

• concave lens

Flashlights, headlights, and a make-up mirror are all examples of

• concave mirrors

• convex mirrors

A convex mirror is curved

• inward

• outward

A concave mirror is curved

• inward

• outward

Store security mirrors and rear view mirrors are both examples of

• concave mirrors

• convex mirrors

The law of reflection states that when light rays strike a plane mirror they are

• reflected at a smaller angle at which they arrived

• reflected at the same angle at which they arrived

• reflected at a larger angle at which they arrived

Glass fibers that transmit light and are used in communication are called

• electromagnetic spectrum

• incandescent light bulbs

• fiber optics

The point in the middle way between a curved mirror and the center of curvature is the

• principle point
• focal point
• center of curvature
• principle axis
