Light Wave Review

An image projected onto a screen at a point where light rays meet is a:

• real image

• diffuse image

• virtual image

• refracted image

The index of refraction is best described as a material’s ability to:

• reflect light

• bend light

• scatter light

• diffuse light

An imaginary arrow that points in the direction that light travels is called a(n):

• image

• view

• ray

• light pipe

Bending of light as it moves from one material to another is known as

• reflection

• refraction

• dispersion

• diffusion

What part of the EM spectrum travels fastest?

• microwaves

• visible light

• x-rays

• all travel at "c"

An electromagnetic wave transmits

• energy but not matter

• matter but not energy

• both matter and energy

• neither energy nor matter

When one uses a magnifying glass to view an object, one is using a —

• converging lens to produce a virtual image of the object

• converging lens to produce a real image of the object

• diverging lens to produce a virtual image of the object

• diverging lens to produce a real image of the object

The angle made by a refracted ray with a perpendicular to the refracting surface.

• reflection

• refraction

• right angle

• bent angle

reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles

• diffuse

• mirror

• convergent

• divergent

The distance from the center of the lens to the principal foci (or focal points) of the lens.

• real

• virtual

• image height

• focal length
