College Waves and Sound
Sound is a transverse, mechanical wave.
  1. True
  2. Flase
College Waves and Sound
Light and RF signals are different in that
  1. light carries less information over fiber than RF can over coax
  2. light is unaffected by interference from lightning or other electrical sources, whereas RF is highly susceptible to these factors
  3. light causes interference with other signals within the cable, but RF does not.
  4. light frequencies are measured to hertz, but radio frequencies are measured in wavelengths.
College Waves and Sound
a light stimulus that is composed of only one wavelength would be said to exhibit
  1. decreased brightness
  2. reduced saturation
  3. hue
  4. reduced contrast
  5. purity
College Waves and Sound
hue is to wavelength as saturation is to
  1. brightness
  2. purity
  3. intensity
  4. threshold
  5. concentration
College Waves and Sound
variation in the                        of a light will result in variation in the perception of                      
  1. saturation; brightness
  2. wavelength; saturation
  3. wavelength; hue
  4. intensity; purity
  5. wavelength; brightness
