Light and Optics Notes

Objects & Light:

Transparent: Light passes through enabling clear vision. Examples: glass, air. High light transmission.

Translucent: Allows some light through but scatters it, causing blurry vision. Examples: frosted glass.

Opaque: Blocks light entirely; light is either reflected or absorbed. Examples: wood, metal.

Reflection:

Regular: Occurs on smooth surfaces, creating clear reflection and images.

Diffuse: Occurs on rough surfaces, light scatters in many directions.

Mirrors:

Convex: Bulges outward, offers a wider field of view, virtual/upright/diminished images. Used in car side mirrors.

Concave: Curves inward, focuses light, image depends on the object's distance.

Far objects: forms Real, inverted, and smaller images.

Close objects: forms Virtual, upright, and magnified images. Used in telescopes, and makeup mirrors.

Lenses:

Convex: Thicker in the middle,
