The correct answer is: D. Infrared ray.
Remote sensing is the acquisition of information about an object or phenomenon, without making physical contact with the object. In remote sensing, the sensing device is located on a platform that is separate from the object being sensed. The platform can be a satellite, an airplane, or a ground-based station.
Infrared rays are a type of electromagnetic radiation that is invisible to the human eye. They have a longer wavelength than visible light, and they can be used to detect heat. Infrared rays are used in remote sensing to measure the temperature of objects on the Earth’s surface. This information can be used to map vegetation, monitor changes in land use, and study the Earth’s climate.
X-rays, gamma rays, and ultraviolet rays are all types of electromagnetic radiation that have shorter wavelengths than infrared rays. They are all capable of penetrating materials, and they can be used to
detect objects that are hidden from view. However, they are also more dangerous than infrared rays, and they can cause damage to human tissue.Therefore, the correct answer is: D. Infrared ray.
