A 1.5mm surface is being measured on an interferometer. A lamp is used which can emit wave lengths as follows. Red: 0.842 um, Blue: 0.6628 um. What are the nominal fractions expected for the gauge for the two wave lengths? Choices:- b) For Blue light, Nf = 0.3568 For red light, Nf = 1.2589 a) For Blue light, Nf = 0.2222 For red light, Nf = 0.9999 c) For Blue light, Nf = 0.2523 For red light, Nf = 0.9454 d) For Blue light, Nf = 0.2666 For red light, Nf = 35.9454
