CHEM 150 Chapter Notes - Chapter 3: Electric Field, Emission Spectrum, Azimuthal Quantum Number
Document Summary
Thermal energy: random motion of atoms and molecules m=mass; u=velocity. Potential energy: possessed by an object by virtue of its position. Chemical energy: stored within the structural units of chemical substances. Electrostatic energy: the interaction of charged particles. Opposite charges = negative e = attraction like charges = positive e = repulsion. Law of conservation of energy: energy can be neither created nor destroyed. = the amount of energy exerted when a force of 1 n is applied over 1 meter. Visible light consisted of electromagnetic waves: electric field + magnetic field = same wavelength & frequency = same speed = travel perpendicularly. Frequency: number of waves that pass through in 1 second. Amplitude: vertical distance from the midline of wave to peak/trough. Double slit experiment interference - when light passes through a slit, a line of light is made through slit. When light passes through 2 slits, series of light and dark lines.
