5 Interesting Facts About Mirrors - That You Probably Didn’t Know

We all look in mirrors every day whether it’s LED Bathroom mirrors to shave in, an illuminated mirror used to apply makeup or a rear view mirror to check who is behind when driving. Aside from their everyday uses mirrors are used for all sorts of weird and wonderful things. Here are a few interesting facts about mirrors that you probably didn’t know:

Fact #1 – In ancient times water was used for mirrors

The first forms of mirrors appeared in ancient times when they would simply use a pool of dark water, or a dark container filled with water. This only changed in around 6000 BC when polished glass began to be used.

Fact #2 – Mirrors reflect sound as well as light

Mirrors that reflect sound waves are known as acoustic mirrors. Before the development of radar, mirrors were used in the second World War to detect sounds coming from enemy aircraft.

Fact #3 – There are mirrors on the moon

A formation of mirrors and lasers on the moon, as well as a telescope down on earth, are used to measure the distance to the moon. This distance changes because of the moon’s elliptical orbit around the Earth, so it is important that such a facility exists.

Fact #4 – Mirrors reflect matter

Mirrors can reflect matter just as they do light. These mirrors are known as atomic mirrors. They use an electromagnetic field to reflect neutral atoms and are used to trap slow atoms or to focus an atomic beam.

Fact #5 – Mirrors can split light

Mirrors can be used to split light and this is why they are commonly used in telescopes and other scientific instruments. These are generally called beam splitters, as a beam of light is focused on the splitter part of the beam will carry on, on its original course while the other veers off at a ninety-degree angle.
