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...
