In physics, a plane wave is a special case of wave or field: a physical quantity whose value, at any moment, is constant through any plane that is perpendicular to a fixed direction in space. For any position in space and any time , the value of such a field can be written as where is a unit-length vector, and is a function that gives the field's value as dependent on only two real parameters: the time , and the scalar-valued displacement of the point along the direction .

WebMay 17, 2024 · In the high-energy limit, photons act more like particles than waves. The intensity is defined as power per unit area, and power is defined as energy per unit time. Thus: I = P A = E Δ t 1 A. The energy of a photon is E = h f, so the total intensity for n photons is I = n ⋅ h f A Δ t. In this model, photons are only counted, and not seen as waves. Webthe direction the plane wave is traveling. For example, if ~k=(0,k,0) the wave is A(x,y,z,t)=A0cos(k(y−vt)+φ) (36) which is a wave traveling in the y direction with angular frequency ω = kv. This plane wave is constant in the x and z directions. Planes waves have direction and phase.

"In physics, the intensity or flux of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m ), or kg⋅s in base units. Intensity is used most frequently with waves such as acoustic waves (sound) or electromagnetic waves such as light or radio waves, in which case the average power transfer over one period of the wave is used.
