Document Summary

Physics compromises a set of laws that describe nature. Understanding physics learning to apply these laws to synthesize new knowledge. Understand the basic concepts and laws of electricity and magnetism and optics. Be able to solve the problems using the basic laws. Electromagnetism is one of the four fundamental forces of nature: others are strong, weak interactions, gravitation. Electromagnetism is responsible for most of the phenomena we encounter in our daily life: Interaction between electrons and protons inside atoms and between atoms determines all the body"s (and other) chemistry: electric machinery (electric motors, power transformers, ekg, mri, radio communications (cell phones, tv, microwave, etc , light. Information technology (internet comprised of current carried by electrons) Electromagnetism in our bodies: electrocardiogram (heart beat, electroencephalography (brain monitoring) Electromagnetism and life: structure and functions of dna. Light waves (details pictured on the right: affects wavelength and wireless communication.
