I am currently taking an optics course and I have been seeing this squiggly symbol of supposed vectors. Are these vectors? In the case of the attached image the squiggly symbol is over B.

Thanks

The squiggly symbol is the tilde. In this case it indicates a complex number called a phasor which is sort of a vector quantity i.e. a number with two components one real and one imaginary A +iB where i = sqrt(-1) This notation is also used in AC circuit theory.
