V=f ? f=V/? f=3×108/ 4×10-7 f=0.75×1015=7.5×1014 Hz
For ?=500nm=500×10-9m=5×10-7 m f=3×108/5×10-7f=0.6×1015=6×1014 Hz
For ?=600nm=600×10-9m=6×10-7mf=3×108/6×10-7f=0.5×1015=5×1014 Hz
2. V=1.73×108f=5.7×1014 Hz?=V/f
In medium: ?=1.73×108/5.7×1014=0.303×10-6 m=303×10-9 m=303 nm
In vacuum: ?=3×108/5.7×1014=0.526×10-6m=526×10-9 m=526 nm
