Why are tinted translucent films applied on window glass panes of passenger buses during hot summer months?
  1. To completely block all visible light from outside
  2. To reduce intense sunlight by allowing only part of the light to enter
  3. To make the glass convert sunlight into electrical power
  4. To make light travel in curved lines inside the bus

Solution

Translucent materials reduce heat and glare by allowing only a fraction of light rays to pass through into the vehicle.
