What is wave theory in remote sensing?
Thus the classica l concept of a wave yields to the idea th at a wave simply describes the probability path for the motion of the individual photons. The particular impor tance of the quantum approach for remote sensing is thatit provides the concept of discrete energy levels in materials.
Which waves are used in remote sensing technique?
For most purposes, the ultraviolet or UV portion of the spectrum has the shortest wavelengths which are practical for remote sensing. This radiation is just beyond the violet portion of the visible wavelengths, hence its name.
What is wave particle theory?
The theory is often called the wave-particle theory. It explains how electromagnetic radiation can behave as both a wave and a particle. The theory posits that waves of photons traveling through space or matter make up electromagnetic radiation.
What is wave theory and particle theory?
Particle theory: Light consists of a stream of small particles, because it travels in straight lines at great speeds is reflected from mirrors in a predictable way. Wave theory: Light is a wave, because it undergoes diffraction and interference (Young’s double–slit experiment).
What is frequency in remote sensing?
Frequency refers to the number of cycles of a wave passing a fixed point per unit of time. Understanding the characteristics of electromagnetic radiation in terms of their wavelength and frequency is crucial to understanding the information to be extracted from remote sensing data.
What are the remote sensing techniques?

What are the 4 types of waves?
Types of Waves – Mechanical, Electromagnetic, Matter Waves & Their Types.
What is the particle theory?
The kinetic theory of matter (particle theory) says that all matter consists of many, very small particles which are constantly moving or in a continual state of motion. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.
What are remote sensing technologies?
Remote sensing is a type of geospatial technology that samples emitted and reflected electromagnetic (EM) radiation from the Earth’s terrestrial, atmospheric, and aquatic ecosystems in order to detect and monitor the physical characteristics of an area without making physical contact.
