| 1. | SPPs are shorter in wavelength than the incident light ( photons ).
 
  | 
 | 2. | The figures show two incident light beams ( A and B ).
 
  | 
 | 3. | Total transmittance is the ratio of transmitted light to the incident light.
 
  | 
 | 4. | The incident light is diffracted by the slits into uniform spherical waves.
 
  | 
 | 5. | It would also depend on the angles of the incident light.
 
  | 
 | 6. | Conventional black paint absorbs about 97.5 % of the incident light.
 
  | 
 | 7. | If the incident light is coherent, these sources all have the same phase.
 
  | 
 | 8. | This could be used for controlling the intensity and direction of incident light.
 
  | 
 | 9. | The transmitted and reflected light is spectrally modified compared to the incident light.
 
  | 
 | 10. | Measurement angle refers to the angle between the incident light and the perpendicular.
