What is Physics?: Mr. Andersen explains the importance of physics as a science. History and virtual examples are used to give the discipline context. Physics uses the scientific method to help uncover the basic principles governing light and matter, and to discover the implications of those laws.
This module discusses the realm of physics (to define what physics is), some applications of physics (to illustrate its relevance to other disciplines), and more precisely what constitutes a physical law (to illuminate the importance of experimentation to theory).
Space for working and answer (b) Applying sunscreen to the skin is one method of protecting people from the Sun’s harmful UV rays. UV radiation can be divided into three wavelength ranges, called UVA, UVB and UVC. A manufacturer carries out some tests on experimental sunscreens P, Q and R to determine how effective they are at absorbing UV ...
