Science Lesson 5 QUIZ Flashcards
(22 cards)
The bouncing back of light into the same medium it has been traveling after striking a surface.
Reflection
The ray that strikes the surface
Incident Ray
The ray that rebounds from the surface
Reflected Ray
A line perpendicular to the surface at the point of incidence
Normal
Reflection from smooth surfaces
Regular or specular reflection
Reflection from rough surfaces
Diffuse reflection
Is one with the flat surface
Plane mirror
Has a reflecting surface taken from the surface of a sphere
Spherical mirror
Curves inward in the direction of the incident rays
Concave mirror
Bulges outward to the incident ray
Convex mirror
Is formed by actual intersection of reflected rays
Real image
Is formed behind the mirror and is upright relative to the object
Virtual image
The center of the sphere from where the mirror was taken
Center of curvature (C)
Center of the mirror
Vertex (V)
Radius of the sphere
Radius of curvature (R)
A straight line joining C and V
Principal axis or optical axis
Width of the mirror
Aperture (AB)
The point where the reflected rays meet as in the cases of a converging mirror
Principal focus (F)
The distance from the vertex to the principal focus
Focal length (f)
The image form by this is never real
Convex mirror
Always virtual, upright, and smaller than the object
Convex mirror
The image form can either be real or virtual
Concave mirror
