SUMMARY
The relationship between intensity and amplitude in wave physics is defined by the principle that intensity is proportional to the square of the amplitude. This is particularly relevant in the context of electromagnetic (EM) waves, where intensity is derived from both the electric and magnetic fields. The discussion references NCERT examples 8.5 and 10.4, which illustrate the concepts of intensity and fringe formation in wave optics, emphasizing the significance of the size of the light source in relation to the slit distance.
