  1. Which observation shows light reflecting from a surface?

    • Seeing a burning candle's flame
    • Seeing the bulb of a lit lamp
    • Seeing your face in a spoon
  2. What do we call light bouncing off a surface?

    • Absorption
    • Reflection
    • Transmission
  3. A smooth mirror can show a clearer picture of your face than a rough towel.

    Circle one:   True   False

  4. Mia's face looks stretched in a shiny spoon but not in a flat mirror. What explains the difference?

    • Her face changes shape when she looks at the spoon
    • The spoon makes its own light instead of reflecting it
    • The spoon's curve changes the reflected picture
  5. Why does still water show Mia's face more clearly than the same water after wind makes ripples?

    • Its smooth surface keeps the reflected pattern clear
    • Its colder water makes extra light inside the puddle
    • Its darker colour stops all light leaving the puddle
  6. You cannot see a rough brick wall because it reflects no light.

    Circle one:   True   False

  7. Sam says a mirror covered with tiny water droplets shows his face as clearly as a clean mirror. Which explanation challenges his claim?

    • Tiny droplets scatter light and blur the picture
    • A warm room stops all light reflecting from glass
    • A clean surface scatters light more than droplets
  8. Zara polishes a scratched metal spoon until its surface is smoother and shinier. What can happen to its reflected picture?

    • The reflected picture becomes much dimmer
    • The reflected picture becomes clearer
    • The spoon begins making its own bright light

Reflecting light W1-mt_gLy3ZgZWiN-s1

  1. Seeing your face in a spoon · To see your face in a shiny spoon, light from your face reflects off the spoon into your eyes.
  2. Reflection · Reflection is light bouncing off a surface.
  3. True · A smooth mirror keeps the reflected pattern clear. A rough towel scatters reflected light in many directions.
  4. The spoon's curve changes the reflected picture · The spoon's curved surface can change the reflected picture's shape. Mia's actual face has not changed, and the spoon remains a reflector.
  5. Its smooth surface keeps the reflected pattern clear · Still water has a smooth surface. Ripples change the surface slopes and distort the reflected picture.
  6. False · A rough wall does reflect light. Some scattered reflected light reaches your eyes, letting you see the wall.
  7. Tiny droplets scatter light and blur the picture · The droplets scatter light and blur the reflected picture. The misted mirror still reflects light.
  8. The reflected picture becomes clearer · Smoothing the tiny scratches reduces the scattering that blurs the picture. The spoon remains a reflector, not a light source.
