You're on a roll — 30. The speed of light (v) in a medium is inversely proportional to its refractive index (n). The relationship is given by the formula: v = (c)/(n) where c is the speed of light in a vacuum. This means that light travels fastest in the medium with the lowest refractive index. Step 1: Identify the refractive indices for each medium. • Medium A: n_A = 1.33 • Medium B: n_B = 1.65 • Medium C: n_C = 1.46 Step 2: Compare the refractive indices to find the lowest value. Comparing the values: 1.33 < 1.46 < 1.65. The lowest refractive index is 1.33, which corresponds to Medium A. Step 3: Conclude which medium allows light to travel fastest. Since Medium A has the lowest refractive index, light will travel fastest in Medium A. The correct option is (A). The medium in which the light will travel fastest is A. What's next? Send 'em! 📸
