Remote Control Reflection

Infrared radiation is widely used in technology, ranging from night vision (in which infrared radiation is detected when there isn’t enough visible light to see an object) to studying the composition of materials through a process called spectroscopy. In this activity, you will explore how the infrared radiation from a remote control interacts with different materials by trying to bounce the IR beam off of a material to control a television from around a corner.
