ENERGY

ENERGY. Energy is the capacity to do work. Potential and kinetic energy are considered types of energy. Kinetic energy is the energy of motion. Potential energy is the energy associated with forces that depend on the position or configuration of a body and the surroundings.

Lasers

Lasers. Instrument Resolution. If observing two distant objects, the diffraction patterns could overlap as shown. Without diffraction, there would be two bright spots on the screen. Resolving Power. The wavelength ( ? ) and the opening size ( D ) determine the resolving power.

Flame Tests for Ions

Flame Tests for Ions Flame Tests Using an Improvised Alcohol Burner Purpose When a metal salt solution is burned, the metal provides a colored flame. Each metal ion gives a different colored flame. Flame tests, therefore, can be used to test for the absence or presence of a metal ion
