Place the response, in the blank, which best completes the following:
______1. When light bounces off of a surface we say it is _____.
______2. Reflection off of a smooth surface, that produces a clear image,
is called a(n) ______refection, in which reflected rays are parallel.
______3. Reflection off of a rough surface, where rays are reflected that are
not parallel, are called _____reflection.
______4. A law that states that a reflected ray has the same angle with the
reflecting surface as its incident ray, is called _____.
______5. Another name for a flat mirror is _____.
______6. The ____ is a luminous source or an illuminated object that
produces an image from a reflecting surface.
______7. An ____ is formed by the combination of light rays coming from
a reflecting surface.
______8. A(n) ______image is one that is always formed on the other side
of the mirror from the object.
______9. _____ rays are those that are moving away from each other.
______10. The image, in a plane mirror, is ___ in the left-right direction.
______11. A(n) _____ mirror is a curved mirror where the inside of the ‘bowl’
is reflective.
______12. A concave mirror can also be called a(n) _____ mirror.
______13. The single ray that enters perpendicular to the center of a mirror is
called the ______.
______14. The single point where parallel light rays intersect, on a curved
mirror, after reflection, is called the ______.
______15. The __ __ is the distance between the mirror and the focal point.
