Do you know…

Know the fascinating Facts….

Why is Water clear?

Water is entirely composed of hydrogen and oxygen. Both elements are gases in nature and are invisible. Being composed of such elusive and invisible elements is certainly a large reason why water has that crystal-clear appearance. However, any discoloration that may appear in water from a natural source such as a river, lake or underground streams such as a well is largely due to natural substances such as algae, leaves, dirt and numerous other particles typically brought in by rainwater.

Why is air Invisible?

Air is a mixture of gases, mainly nitrogen and oxygen with small molecules (particles) that are far apart. Wavelengths of light may pass by these molecules without hitting them. When they do bump a molecule, it absorbs some colour and scatters some, spreading it out in all directions. But this is too little to reach our eyes for us to notice, thus making air appear invisible

Why do distant objects look smaller?

The easiest way to understand this is by thinking about something called your field of view. This is how much you can see, without turning your head. When things are closer to you, they take up more of your field of view, so they seem bigger. When they’re further away, they take up less of your field of view, and so seem smaller.

Why are vehicle Taillights usually coloured red?

Functionally red light has less effect on human low light vision than any other visible colour. Red tail and brake lights are highly recognisable to the Rod cells in our eyes, while higher wavelength colours like green or blue are harder to distinguish.
