SCIENCE PLANE MIRROR

is formed by the actual intersection of reflected rays. It is formed outside or in front of the mirror and is always inverted.

Real image

is always formed behind or inside the mirror, it is always upright. There is no actual intersection of reflected rays in virtual images

virtual image

When light rays hit the concave mirror, if they’re directed toward the center of curvature, they’ll reflect back along the same path.

Center of curvature

point where parallel light rays that hit the concave mirror converge after being reflected.

Focal point or Principal focus

Light rays diverge after reflecting off the surface. they don’t actually meet, but they appear to come from a point behind the mirror.

Virtual focus

Why is it virtual focus?

Because there is no actual light rays pass through this point

the portion of the mirror’s surface that reflect lights.

aperture

the larger the aperture, the more _______ the mirror can reflect.

light rays

straight line that passes through the center of curvature and the vertex

Principal axis

where the principal axis meets the mirror’s surface

vertex

reflect parallel light rays inward

concave mirror

a mirror causing them to converge at the focal point, which is a real focus

Concave mirror

reflect parallel lights outward, making them diverge

Convex mirror

mirror where they appear to come from a virtual focus behind the mirror

Convex mirror
