Refraction results from differences in light's
In an experiment used to demonstrate refraction, monochromatic light is transmitted through a transparent block with a refractive index of 1.4, which changes the speed of the light.If it's wavelength is 625 nm ( [math: 1nm=1×10−9m] 1nm = 1 \times 10^{-9} m ) in the block, determine the frequency of the light.Answers below are given in petaHertz, PHz ( [math: 1×1015Hz] 1 \times 10^{15} Hz ).
