The nature of physical phenomena with an experienced observer

This guide examines the physics of various natural phenomena. Some of them you have observed many times. Nature is diverse and truly boundless, so it is simply impossible to cover this topic exhaustively. The manual covers only some natural phenomena-those that seemed most interesting and are consistent with the relevant sections of the school physics curriculum. Studying the physics of natural phenomena is of great cognitive value. It is nature that demonstrates the conventionality of dividing physics into separate independent sections and the interconnection of physical phenomena. For example, if we consider a thunderstorm, we encounter the simultaneous manifestation of the laws of mechanics, hydrodynamics, thermodynamics, molecular physics, electrostatics, electrodynamics, acoustics, and optics. Modern people know, at least in general terms, how a car engine works. However, not everyone knows why the sky is blue, how a thundercloud forms and dissipates, why there are double rainbows, what a green flash or a halo is...
