PROPERTIES OF LIGHT PSCIW4

• Light is the type of radiation that is visible to human eyes. It also measures electron.
• Transmission of light is the passing of light without absorption. An example is passing of light through glass.
• What affects the transmission is the object where the passing of light happens.

  glass = transparent, clear

  frosted glass = translucent, blurry

  wood = opaque, absorption
• Absorption is when the energy is taken up by the object's atoms
• In absorption, light energy is converted to thermal energy.
• White light is composed of the colors - ROYGBV
• In absorption,

  absorbed light = black

  reflected light = white
• In absorption of the leaf, ROYBV were absorbed except green
• DISPERSION is the seperaion of white light into colors due to the bending of light/refraction.

  
• Light is a transverse wave because it is electromagnetic wave
• A wave is a disturbance of a medium
• transverse waves are perpendicular to the direction of wave propagation
• parts of wave

  A) wavelength

  B) crest

  C) amplitude

  D) trough

  E) wavelength
