Radiation: Radiation Using Parabolic Mirrors

PIRA Class: 4B40.10

Purpose: 

Two parabolic mirrors are placed on the table. One has a heating coil at its focal point and the other has a candle and match at the focal point. When the heating coil is on, there is enough radiated heat to light the match and candle.

Description:
Place the parabolic mirrors parallel to each other at each end of a table. Turn the Variac all the way up and after ~30 seconds, the match will start smoking and after ~45 seconds it will burst into flames.

Equipment:
Parabolic mirror with match holder assembly, Variac
