13. Compute the change in the refractive index of a medium induced by an external electric field, where the change (n) is given by the formula: n = n2E2 (n0) Here, n2 is the second-order nonlinear refractive index coefficient, E is the electric field strength, and n0 is the baseline refractive index. Given: - n2 = (3.2 0.4) 1016 cm2/V2 - E = (1.00.05)104 V/cm - n0 = (1.500.02) Calculate n and determine the correct error bars considering the order of operations (mul- tiplication followed by subtraction)
