Define: Pixel, Swath, Orbit, Atmospheric Window. List processes when light energy interacts with Earth's surface.

Here are the definitions and processes:

7. Define the following: i. Pixel: A pixel is the smallest individual unit of a digital image, representing a single point in a raster image and typically storing color or intensity information. ii. Swath: A swath is the area on the Earth's surface imaged by a remote sensing instrument in a single pass. It represents the width of the ground coverage. iii. Orbit: An orbit is the curved path, usually elliptical, that a satellite or spacecraft follows around a celestial body, such as the Earth, under the influence of gravity. iv. Atmospheric window: An atmospheric window is a range of wavelengths in the electromagnetic spectrum where the atmosphere is relatively transparent, allowing electromagnetic radiation to pass through with minimal absorption or scattering.

8. The potential processes that occur when light energy interacts with the surface of the Earth are:

• Absorption: The surface material takes in the light energy, converting it into other forms like heat.
• Reflection: The light energy bounces off the surface without being absorbed, changing its direction.
• Transmission: The light energy passes through the surface material.
