Infinity Learn · Accepted Answer

According to Einstein's equation, $$hv=hv0+eV$$⇒ $$V=hev$$−$$v0Given$$ $$V1=hev1$$−$$v0$$ and $$3V1=he2v1$$−$$v0$$⇒ $$3V1V1=2v1$$−$$v0v1$$−$$v0$$⇒$$v1=2v0$$∴ $$V1=he2v0$$−$$v0=hev0At$$ frequency $$4v1$$, $$nV1=he4v1$$−$$v0$$                                  $$=he8v0$$−$$v0=7$$×$$hev0$$⇒ $$nV1=7V1$$⇒$$n=7$$
