How to Deflect a Laser Beam With a Mirror

A laser is essentially concentrated light focused in one specific area. Although there are different concentrations and powers of a laser, it is possible to purchase some of the weaker lasers, most notably in the form of a laser pointer. A laser beam, like any other form of light, can be reflected and deflected by being bent by a series of mirrors. This can be a fun science experiment to teach children in school.

Things You'll Need

• Laser pointer
• Tape
• Mirror

Instructions

1. Power on the laser you are using. If you are using a laser pointer and the device does not have a power button that stays on, you can wrap some tape around the button. This applies pressure to the button, keeping the laser on.

2. Position the laser to point the direction you want it to. If the mirror is stationary and installed on a wall, you can point the laser directly at the wall. Place the laser on a table or other solid, flat object to hold it steady.

3. Use a small mirror, this can be a makeup mirror or any other mirror that is portable, and hold it in the path of the laser. This will deflect the laser back in the opposite direction.

4. Move the mirror until you are deflecting it in your desired direction.

5. Repeat the process with a different mirror if you want to. You can deflect the laser beam as many times as you like.
