  1. 1. (a) straight lines — Light travels in straight lines.
  2. 2. (b) opaque — Such an object is opaque.
  3. 3. (c) outline — A shadow shows the shape/outline only.
  4. 4. (d) translucent — It lets some light through but is not clear.
  5. 5. In straight lines (rectilinear propagation).
  6. 6. The bouncing back of light from a surface.
  7. 7. A shadow is the dark region formed behind an opaque object when it blocks the path of light. Because light travels in straight lines, it cannot bend around the object, so the region directly behind it receives no light and appears dark. A shadow shows only the outline or shape of the object, not its colour or surface detail, which is why shadows of differently coloured objects of the same shape look alike. The size and direction of a shadow change with the position of the light source — a light source close to the object or low down produces a longer shadow. Shadows are thus direct evidence that light travels in straight lines.
