LIGHT and SOUND
Light comes from the sun. Light also comes from different sources like electric lamps, fires and torches.
Light rays cannot bend around things.
All light travels in straight lines.
Light travels in lots of straight lines called rays.
Shadows are made when light is blocked by an object.
When an object is close to a light, it blocks more of the light rays.
The object then makes a big shadow.
When the object is far away from the light, it makes a smaller shadow.
When light falls on some objects it is reflected. That means, it travels backwards after hitting the object.
Smooth, shiny objects reflect more light.
