Document Summary
An equation is a concise way to state the relationships between different quantities. An equation is also like a balancing scale-the quantities on one side of the equal sign must balance the quantities on the other side. For example, the size of the gravitational force of attraction between two bodies (let"s call it. M1 and m2 are the masses of the two bodies. D is the distance separating the centres of the two bodies. G newton"s gravitational constant (a fixed number) If i increase m1, then f1->2 must increase by the same factor. If i increase d, then f1->2 must decrease by the same factor squared. Light passing through a prism bends at different angles for every wavelength. A diffraction grating reflects (or transmits) light at different angles for different wavelengths also, but with greater dispersion (bending) Three categories of spectral features can be present: the spectrum of an object gives clues about how the light was produced.
