1. Diffraction is
     created from a powerful beam of light through stimulated emission of radiation
     the bending of light around an object in it's path
     emitted by every single thing, with its amounts based on the object's temperature

2. A good example of diffraction is
     a shadow
     a mirror
     a rainbow

3. Far away objects appear blurry because
     our eyes are not strong enough
     waves can not travel large distances
     light is bent to get around the objects

4. Diffraction gratings are used to figure out
     the wavelength of the light passing through the grates
     the frequency of the light passing through the grates
     how much light is passing through the grates

5. The spacing of the lines in a diffraction grating can be calculated by
     determining the lines per mm and dividing 1 by that number
     determining the lines per cm and dividing 1 by that number
     determining the lines per in and dividing 2 by that number

6. The more lines in a grating, the
     dimmer the image it gives
     fuzzier the image it gives
     sharper the image it gives

7. Wavelength in a grating can be found using the equation
     Wavelength=d*sin theta
     Wavelength=a*sin theta
     Wavelength=c*sin theta

8. White light turns into
     the spectrum
     wavelengths
     pigment
