Document Summary

Chapter 5 key concepts y rate of energy flow is called power, and it s measured in watts y a spectrum is the rainbow of light split from a prism. It forms white light when all the colours are mixed y light interacts with matter in 4 basic ways: emission: when a light source emits visible light. A light bulb: absorption: when something is put near a light source and that thing absorbs some of the light, warming the object. Materials that absorb light are called opaque: transmission: some forms of matter transmit light, letting it go through. Materials that transmit light is called transparent: reflection/scattering: light can bounce off matter. Shortest highest: the three basic types of spectra are called: Continuous spectrum y rainbow of colour, broad range of wavelengths without interruption. emission line spectrum y when a thin or low density cloud only emits light at specific wavelengths depending on the cloud s composition and temperature.

With two Polaroid filters, specially fabricated plastic sheetshaving the property that they transmit light which is linearlypolarized along a certain direction—called the “polarizationdirection” of the filter—determined by material properties of theplastic sheet. Conversely, Polaroid filters absorb light polarizedat right angles to the polarization direction.
Now look at other sources of reflected light through one of yourfilters. What happens to the polarization of light scattered orreflected from a vertical surface? What does this imply about theprocess of scattering or reflection? Look at different materialsurfaces, such as metal, glass, leaves, Is blue skylight polarized?In what direction? Are clouds polarized? When back inside, checkthe polarization of other sources of light: light bulbs,fluorescent lights, computer screens, Is there a difference betweenCRT and LCD computer screens?

2.We wish tocoat a flat slab of glass (n = 1.50) with a transparentmaterial (n= 1.25) and illuminate with light of wavelength 600 nm(in vacuum).For what minimum thickness of the coating will thelight be (a)reflected back to the observer and (b) transmittedthrough the glass(i.e. no reflection back to the observer)? [Note:t = 0 is not ananswer for (b)].
