The Angle between the incident ray and the normal line is known as the __

• angle of incidence

• angle of reflection

• normal line

The Angle between the reflected ray and the normal line is known as the __

• Angle of Incidence

• Angle of Reflection

• Normal Line

An imaginary line that can be drawn perpendicular to the surface of the mirror at the point of incidence where the ray strikes the mirror.

• Incident Ray

• Reflected Ray

• Normal Line

It is the bouncing off of light rays when it hits smooth or rough surfaces like plane mirrors, paper, concrete walls, etc.

• Reflection

• Refraction

• Dispersion

• Diffraction

This is a reflection of light on smooth surfaces such as mirrors or a calm body of water.

• Regular

• Irregular

• Diffused

This is a reflection of light on rough surfaces such as clothing, paper, wavy water, and the asphalt roadway.

• Regular

• Specular

• Irregular or Diffused

What relationship exists between the number of images formed and the angle between two mirrors?

• As the Angle between two mirrors decrease, the number of images also decrease.

• As the Angle between two mirrors decrease, the number of images increase.

• As the Angle between two mirrors increase, the number of images also increase.

What is the correct formula in determining the number of images between two plane mirrors?

• N= 1- (360/angle between mirrors)

• N= (360/90o) -1

• N= (360/angle between mirrors) -1

• N= (180/angle between mirrors) -1

This optical instrument allows sea navigators in a submarine to see the surface of the water.

• Periscope

• Telescope

• Microscope

• Camera

Why can’t you see your face on the pages of your lecture notebook? When light hits paper,

• the waves are reflected in only one direction.

• the waves are reflected in all directions.

• . the waves are refracted.

• the waves are dispersed.
