A Certain Type of Glass Is Used in Making Flat-Panel $\lambda$

Multiple Choice

A certain type of glass is used in making flat-panel computer monitors. For light with a wavelength in air of 656.3 nm, the refractive index of the glass is n_A = 1.5160. For light with a wavelength in air of 435.8 nm, n_B = 1.5290. Determine the difference, $\lambda$ _A- $\lambda$ _B, in their wavelengths inside the glass.

A) 147.9 nm
B) 156.0 nm
C) 220.5 nm
D) 268.4 nm
E) 293.1 nm
