Step 1: Determine the slope (m). The calculation for the slope is provided in the image. m = (1.2 - 0.4)/(2.0 - 0.5) m = (0.8)/(1.5) m ≈ 0.533 The slope is 0.533. Step 2: Calculate _e. Using the given formula _e = (1)/(m): _e = (1)/(0.533) _e = (1.5)/(0.8) _e = 1.875 The value of _e is 1.875. Step 3: Physical significance of _e. _e represents the refractive index of the medium. It is a dimensionless quantity that indicates how much the speed of light is reduced when passing through the medium compared to its speed in a vacuum. A higher refractive index means light travels slower and bends more when entering the medium. Step 4: Precautions. • Ensure the pins are vertical to accurately mark the light path. • Use a clean glass block free from smudges or scratches to prevent light distortion. • Draw thin, sharp lines for the incident ray, refracted ray, and normal to minimize measurement errors. • Avoid parallax error when reading angles from the protractor by viewing directly perpendicular to the scale. • Ensure the normal line is drawn accurately at the point of incidence, perpendicular to the surface.
