What type of tracking energy includes laser and infrared?

The correct answer, which identifies the type of tracking energy that includes laser and infrared, is light energy. This is because lasers operate on principles of light, emitting coherent streams of photons, which are the basic units of light. Similarly, infrared energy is part of the electromagnetic spectrum, which includes various wavelengths of light that are invisible to the human eye but can be detected as heat.

In the context of tracking systems, both laser and infrared technologies work by utilizing the properties of light to measure distances or detect objects. For example, laser rangefinders use the speed of light to determine how far away an object is based on the time it takes for the light to travel to the object and back. Infrared sensors can detect heat emitted by objects, which is also a function of light energy in the form of thermal radiation.

Understanding this classification of energy is crucial for applications in various fields, such as military, surveillance, and even everyday technologies like remote controls and thermal cameras. This highlights the importance of light energy as a critical factor in tracking technology.
