Untitled Flashcard Set

Light

● What is light: Electromagnetic spectrum, Wavelength & Frequency

● Linear transmission

● 5 sources of light

● Measuring the speed of light: Galileo, Roemer, Fizeau (don’t need detail, just general approach)

● Luminous vs. non-luminous objects

Reflection

● 2 types of reflection

● 3 types of mirrors

● 3 things that can happen when light strikes a surface

Refraction

● Why light bends passing into different media, and connection with speed of light

● Dispersion

● Total internal reflection

Lenses

● Distinguishing converging & diverging lenses

● Thin lens approximation

● Focal plane

Ray Diagrams

● Plane mirrors

● Concave & Convex mirrors

● Converging & Diverging lenses

● Characteristics of Images: Size, attitude, location, and type

Calculations

● Angle of reflection (ex: in a plane mirror)

● Angle of refraction (Snell’s Law)

● Index of refraction ( )

● Magnification equation: object & image height, object & image distance, magnification for

convex/concave mirrors and converging/diverging lenses ( )

● Mirror equation/Thin lens equation: focal length, image distance, and object distance for

convex/concave mirrors and converging/diverging lenses ( )

Applications

● Refraction: fishing, bent straw, inferior mirage, superior mirage, oval sunrise/sunset

● Rainbows: dispersion, refraction, and total internal reflection. Primary & secondary rainbows

● Concave mirrors: headlight, satellite dish, make-up/shaving

● Convex mirrors: security, car side-view

● Lenses: magnifying glass, 3 types of telescopes, microscope
