Light travels in straight lines. When light hits an object, it is reflected (bounces off) and enters our eyes. This is how we
see the object.
When light from an object is reflected by a surface, it
changes direction. It bounces off the surface at the same
angle as it hits it.
Smooth, shiny surfaces such as mirrors and polished metals
reflect light well. Dull and dark surfaces such as dark fabrics
do not reflect light well.
Reflective surfaces can be very useful. Mirrors inside cars
reflect light to help drivers see objects behind them.
Reflective strips on clothing and bikes help cyclists to be
extra visible at night. ‘Cat’s eyes’ on the road reflect light
from car headlamps to help the driver see the road at night.
