  • What is happening to the light?
    absorbing
  • What will light do when it hits this medium?
    refract
  • What does horizontal mean?
    side to side
  • refraction is when light
    appears bent or broken as it travels through a medium
  • What is happening to the light?
    reflecting
  • Why can we see the moon at night?
    It reflects light from the Sun
  • Which colors are being reflected?
    red and green
  • mechanical energy is the energy of
    motion/movement
  • What is happening to the light?
    refracting
  • Sound is heard when energy transfers between particles that ______________ and reaches our ears
    vibrate against each other
  • What will light do when it hits this medium?
    reflect
  • Why does the lightbulb not work in this circuit?
    It is not connected on both sides.
  • What will happen if you remove one of the lightbulbs?
    the other will turn off because they share a pathway
  • How does light travel?
    in a straight line
  • What will light do when it hits this medium?
    absorb
  • Explain this circuit
    Each light has its own path and its own switch.
  • What is happening to the light?
    refractiing
  • What does vertical mean?
    up and down
  • If the lightbulb on the right goes out, what will happen the lightbulb on the left?
    It will remain lit.
  • A change in motion means that energy has been
    transferred
  • Which color is being reflected?
    green
  • Which lightbulbs does this switch control?
    both
  • In water, energy is transferred between the water particles. The waves are moving ________________________.
    up and down (vertically)
  • Explain this circuit
    Each light has its own path but both are controlled by the same switch
  • What is happening to the light?
    reflecting
  • thermal energy is the energy of
    heat
  • What will happen if you remove one of the lightbulbs?
    the other will stay on because it has its own pathway
  • Which lights would turn on in this circuit?
    Lightbulb 1 only
  • Sound waves move __________________ as they transfer.
    horizontally (side to side)
  • reflection is when light
    bounces off a surface or medium
  • What will light do when it hits this medium?
    reflect
