Study Notes

Reflection of Light

Incident Ray: A ray of light traveling toward a surface
Angle of Incidence: The angle between the incident ray and the normal line.
Normal: A line perpendicular to the surface at the point where the ray strikes.
Reflected Ray: A ray that bounces off the surface, originating at the point where the incident ray meets the normal.
Angle of Reflection: The angle between the reflected ray and the normal.
Plane Mirror: A mirror with a flat reflective surface.
Reflection: The change in direction of a wave as it bounces off a surface.

Shadows

Shadows: Formed when light is blocked by an opaque object.
Object Proximity and Shadow Size: Objects closer to the light source produce larger shadows; objects further away, smaller shadows.
Light Straight-Line Travel: Light travels in a straight line as long as it remains in the same medium.
Medium: The substance through which light travels.
