This is obviously an idealized situation and we know that the radiation from an ordinary light source consists of finite* size wave trains, a typical time variation of which is shown in Fig. 5.1. As can be seen from the figure, the electric fields at times . and . + Δ. will have a definite ph

Variability of Air Temperature,sensitive material reacts to the . of light falling on it and consequently, after developing and fixing of the photographic plate, one obtains a permanent record of the intensity distribution that existed at the plane occupied by the photographic plate when it was exposed. In this process, the phase

Variability of Air Temperature,g which the self-focusing of intense laser beams occupies an important place because of its relevance to other nonlinear effects. The self-focusing effect arises primarily due to the dependence of the refractive index of a material on the intensity of the propagating electromagnetic wave. This nonli
