Orange,violet and yellow have different frequencies. How can we see them, as we have only three receptors rgb?

Merely combining those frequencies cannot generate a new one.

    $\begingroup$ This question has rather detailed answers in the physics community. In a nutshell - they don't see other frequencies, but rather the color is determined by our brain by the relative excitation of different cones. $\endgroup$
