Light and optics test

Law of Reflection

The angle of incidence equals the angle of reflection.

Image in a plane mirror

Virtual and upright.

Convex lens and parallel ray

It converges at the focal point on the opposite side.

Concave lens image

Always forms a virtual, upright, and smaller image.

Image produced by a convex lens between F and the lens

Virtual, upright, and larger.

Ray through optical center of a lens

Ray passing through the optical center.

Concave lenses behavior

They diverge parallel rays.

Lens calculation formula

1/f = 1/do + 1/di.

Negative image distance (di)

The image is virtual.

Magnification (M) value of -2

The image is inverted and twice the size.
