Question

The speed of light in vacuum is c = 3 times 10^8 m/s. A specific medium has an index of refraction n = 1.6. Randomized Variables n = 1.6 Part (a) Express the speed of light in this medium, v, in terms of c and n. Expression: v = ___ Select from the variables below to write your expression. Note that all variables may not be required. alpha, beta, theta, a, c, d, g, h, i, j, k, m, n, P, t Part (b) Solve for the numerical value of v in m/s. Numeric: A numeric value is expected and not an expression. v = ___

Explanation / Answer

(A) Speed of light in medium of refractive index n,

v = c / n

(B) putting values,

c = 3 x 10^8 m/s and n = 1.6

v = (3 x 10^8) / 1.6

v = 1.875 x 10^8 m/s
