Optics

refraction is waves bending because of

• edges of a slit or thin object

• speed of wave changes

• dark matter

• gravity

which mirror ALWAYS shows things right side up

• convex

• concave

• diverging

• converging

which type of lens will help correct this vision problem (Myopia- nearsightedness)

• convex

• concave

• opaque

• plano

The angle of incidence is equal to the angle of reflection

• Law of Reflection

• Law of Light

• Incidence Ray

• The Normal

Light always travels in a

• straight line

• wavy line

• curved line

• zig-zag line

The point at which the light rays meet is called the

• principle point

• focal point

• center of curvature

• principle axis

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?

• convex lens

• concave lens

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

• concave mirrors

• convex mirrors

Store security mirrors and rear view mirrors are both examples of

• concave mirrors

• convex mirrors
