Law of reflection

• The angle of incidence is greater than angle of reflection

• The angle of incidence is equal to angle of reflection

• The angle of incidence is equal to angle of refraction

• The angle of incidence is less than angle of reflection

The reflected rays are parallel to each other.

• Specular reflection

• Diffuse reflection

• Total internal refraction

• Specular refraction

It is the line perpendicular to the surface. It is at the point where the incident ray strikes the surface.

• Reflection line

• Ray line

• Angle of reflection

• Normal line

Index of refraction always is greater than or equal to one.

• True

• False

It is a particular angle of incidence that will result in an angle of refraction of 90°

• Normal angle

• Critical angle

• Angle of refraction

• Angle of incidence

The total internal reflection occurs when light goes from a medium toward one having a lower index of refraction

• False

• True

This image is formed when light rays pass through and diverge from the image point.

• Virtual image

• Light image

• Both are correct: real and virtual

• Real image

It is the ratio of image height and object height.

• Index of refraction

• Index of reflection

• Lateral magnification

• Image

When magnification (M) is less than one (1) means that image ...

• ... is inverted respect the object.

• ... is larger than the object.

• ... is smaller than the object.

• ... has same orientation as the object.

In this picture ...

• Image is real

• Magnification is less than 1

• Magnification is negative

• Magnification is positive
