![]() The power and amplitude of a wave will determine its intensity. Watts per square meter is the most used measurement unit. Let’s examine each of these characteristics. It is equal to the energy density multiplied by the wave speed. The photoelectric effect has three important characteristics that cannot be explained by classical physics: (1) the absence of a lag time, (2) the independence of the kinetic energy of photoelectrons on the intensity of incident radiation, and (3) the presence of a cut-off frequency. The quantity of energy carried by a wave per unit time across a unit area surface is known as intensity. Let’s take a look at the concept, Intensity Formula With examples, we’ll go over sound intensity and the intensity formula in this post. Sound intensity is the relevant physical quantity, and this concept holds true for all noises, whether heard or not. These are also linked to the source’s energy vibrations. These examples demonstrate the loudness of sounds and, as a result, the intensity of sound. When a passing motorist’s radio is turned up, though, a person can’t hear what the person in the car next to them is saying. When people are in bed at night, they may hear our blood rushing through our ears. Occasionally people can hear a single leaf fall to the ground in a peaceful forest.

Thus one can say that light has ‘emerged’ from the solution of Maxwell equations.
