In the home
In the home

Concave makeup mirrors / shaving mirrors magnify the image (when you are in front of the focal point)


At the Dentist – enlarged image of a tooth

Inside a flashlight to send out parallel light rays


Solar ovens
Solar Ovens

Sunlight is free!

Solar radiation is reflected from a concave mirror to the focal point

Temperatures can reach up to 200 deg. C


Archimedes death ray

Acoustic mirrors sound waves
Acoustic Mirrors (sound waves)

Built and used before World War 2 in Britain to hearenemy aircraft (1930s)

Sound (not light) reflected to microphone

No longer used after radar was invented


Radar technology
Radar Technology

Concave “dish” that sends and receives radio waves

Radio waves are sent out and any waves bounce off of aircraft are reflected from the mirror to the receiver at the focal point.

Stealth aircraft can be constructed with small flat surfaces and many angles so they can avoid detection


Security convex mirrors
Security – Convex Mirrors

Store security –the store clerk can see what is going on from the counter

Border crossings, event security – check the undersides of vehicles
