TRUE OR FALSE

• Just like sound, light is an electromagnetic wave that does not need a medium to spread but can still be reflected, transmitted, or absorbed.

  FALSE, sound is not an electromagnetic wave
• Isaac Newton and Christiaan Huygens both believed that light is a stream of particles. They called them Corpuscles.

  FALSE, Huygens believed that light is a wave
• Light behaves as a wave, or as particles, depending on what we do with it, and what we try to observe.

  TRUE
• Rectilinear propagation of light means that light spreads inversely proportional with distance.

  FALSE, it means that light travels in a straight distance
• Illuminated Areas gets larger as distance from light source gets farther

  TRUE
• Rainbows are created through dispersion of white light.

  TRUE
• The color violet has the shortest wavelength, so it has the shortest frequency.

  FALSE, short wavelength = long frequency
• Light is an electromagnetic wave that is composed of 6 different colors.

  FALSE, light has 7 different colors (ROYGBIV)
• As we get farther away from a light source, the illuminated area becomes smaller.

  FALSE, Illuminated area gets larger but intensity weakens
