Plasma physics is the study of a state of matter comprising charged particles. Plasmas are usually created by heating a gas until the electrons become detached from their parent atom or molecule.

\(power \ of \ a \ lens \ (D) = \frac{1}{focal \ length \ (m)}\) A lens has a power of -3.33 dioptres. Calculate the focal length and state what type of lens it is.

The most commonly used and the earliest example of an achromatic lens is the achromatic doublet. An achromatic doublet is made from a pair of glasses, of which one is typically a concave and another ...
