Orange light of wavelength 0.61 µ m in air enters a block of glass with εr = 1.44. What color would it appear to a sensor embedded in the glass? The wavelength ranges of colors are violet (0.39 to 0.45 µ m), blue (0.45 to 0.49 µ m), green (0.49 to 0.58 µ m), yellow (0.58 to 0.60 µ m), orange (0.60 to 0.62 µ m), and red (0.62 to 0.78 µ m)
