4B40.10light the matchPIRA 200Light a match at the focus of one parabolic reflector with a heating element at the focus of another reflector.
4B40.10light the match4B40.10Two parabolic reflectors are aligned across the table, a heat source at the focus of one reflector and a match at the focus of the other.
4B40.10light the matchTPT 28(1),56Use a homemade nichrome wire coil for the light the match demonstration.
4B40.10transmission of radiant heatHf-5A match at the focus of one parabolic reflector is lit by a heating element placed at the focus of another reflector.

4B40.11reflection of radiation38-5.9A beam from a heated metal ball in the focus of a parabolic mirror reflects off another parabolic or flat mirror to a thermopile.
4B40.11radiation reflectorH-3cA heat source at the focal point of one concave reflector directs heat at a radiometer at the focus of a second concave reflector.
4B40.12beakers of water at a distance38-5.10A thermopile. mounted the at focus of a parabolic mirror detects radiation differences from different colored beakers of water at 20'.
4B40.13reflection of radiationH-149Polished sheet metal is used to reflect radiation onto a thermopile. A plate glass mirror is less effective due to IR absorption.

4B40.40two can radiationDisc 14-24Shiny and flat black cans filled with cool water warm up, cool off when filled with boiling water.
4B40.45radiation from a shiny and black surHf-4A paper held close to a stove element is not scorched where the element is painted white.
4B40.45stove element38-5.3A sheet of paper is held near a stove heating element painted half white and half black.
4B40.48hot wire in a tube38-5.6A platinum wire is heated inside of a quartz tube showing transparent objects radiate less.
