Geometric Optics

Your image behind a plane mirror is at a distance equal to

• half your height.

• half your distance from the mirror.

• your distance in front of the mirror.

• slightly more than your distance in front of the mirror.

Refraction occurs when a wave crosses a boundary and changes

• speed and direction.

• intensity.

• frequency.

• amplitude.

What type of image does this lens form?

• Virtual image
• Real Image
• No Image

• inverted and diminished

• inverted and magnified

• upright and diminished

• upright and magnified

• 0.4132

• 10.057

• .4226

Refracted light that bends away from the normal is light that has
