Remote sensing uses which of the following waves in its procedureQuestion 1AnswerA.Electric fieldB.Electro-magnetic wavesC.Gamma-raysD.Solar waves
Solution
The correct answer is B. Electro-magnetic waves.
Remote sensing works by recording the electromagnetic radiation (a form of energy) that is reflected or emitted by the Earth’s surface. This can be done from aircraft or satellites, which carry sensors that can capture data about the Earth's surface. These sensors can capture data in multiple wavelengths of the electromagnetic spectrum, which includes visible light, infrared, and microwave.
