Alpha, Beta, Gamma

Introduction, $\alpha, beta, gamma -\text{rays} \dfrac{n}{p}$ ratio etc.

Alpha is the first Greek first alphabet. It has the value of 1 in greek mumerals.The letter alpha represent various concepts in mathematics, physics and chemistry. Alpha also stands for thermal expansion coefficient. Gamma is the third greek alphabet. It has the value of three.
