Intensity and wavelength equation
Nettet12. sep. 2024 · Equations 9.5.5 and 9.5.6 are known as the plane wave relationships. The plane wave relationships apply equally well to the phasor representation of bfE and H; i.e., ˜E = − ηˆk × ˜H ˜H = 1 ηˆk × ˜E. These equations can be readily verified by applying the definition of the associated phasors (e.g., Equation 9.5.3 ). NettetThe intensity I ( λ, T) of blackbody radiation depends on the wavelength λ of the emitted radiation and on the temperature T of the blackbody ( Figure 6.3 ). The function I ( λ, T) is the power intensity that is radiated per unit wavelength; in other words, it is the power radiated per unit area of the hole in a cavity radiator per unit wavelength.

Recall that wavelength is defined as the distance between adjacent identical parts of a wave. The wavelength of a sound, therefore, is the distance between adjacent identical parts of a sound wave.
Nettet12. sep. 2024 · We are given d = 0.0100 m m and θ = 10.95 o. The wavelength can thus be found using Equation 3.3.2 for constructive interference. Solution Solving Equation 3.3.2 for the wavelength λ gives λ = d sin θ m. Substituting known values yields λ = ( 0.0100 m m) ( sin 10.95 o) 3 = 6.33 × 10 − 4 m m = 633 n m.
