I know that half silvered mirrors are used in the production of laser emission. Can half silvered mirrors be used outside the instrument so the rays get reflected back on one side of the mirror and pass through the other side?
What will be the result if a half silvered mirror is kept rotating and laser is made to pass through it?
Similarly what will be the result if a prism is kept rotating and laser is made to pass through it?
Series of prisms and mirrors are used in the instrument to produce laser but can we obtain more patterns (movement of laser in entertainment lasers) when we keep a rotating half silvered mirror and prism (different cases) and laser is made to pass through it?
