  • Question 1

Is this statement true or false?

Powerful electric lights may seem brighter than the sun.

CORRECT ANSWER
true
EDDIE SAYS
Electric lights are much closer to us that the sun which is millions of miles away. Large floodlights at a pop concert, for instance may seem brighter than the sun, but actually the sun is hugely brighter than any electric light.
  • Question 2

Is this statement true or false?

CORRECT ANSWER
true
EDDIE SAYS
Electric lights are much closer to us that the sun which is millions of miles away. Large floodlights at a pop concert, for instance may seem brighter than the sun, but actually the sun is hugely brighter than any electric light.
  • Question 3

Is the statement true or false?

Candles make light by burning wax. 

CORRECT ANSWER
true
EDDIE SAYS
Paraffin wax is a solid fuel. A match will melt the wax and the liquid wax passes up the wick to be burned to make Carbon dioxide and water vapour. Some of the energy is converted into light.
  • Question 4

Is this statement true or false?

Owl's eyes give out light so they can see in the dark.

CORRECT ANSWER
false
EDDIE SAYS
Owl's eye doesn't give out light, but they have night vision which makes them able to see when it's very dark.
  • Question 5

Is this statement true or false?

You should never look at the sun directly, it can make you blind.

CORRECT ANSWER
true
EDDIE SAYS
There are ways of looking at the sun safely. The best way for amateurs is to use an image that is projected through a telescope or one lens of binoculars onto a sheet of paper. It is safe to look at the sun in the late evening as it is setting or just as it is rising because it is appearing through a much thicker layer of atmosphere. This cuts out a lot of the brightness.
  • Question 6
