Questiоn 3.2 A student uses а semicirculаr glаss blоck tо investigate refraction in glass. He shines a ray of light into the block, at point P, as shown. Right click to open the image in a separate window. (i) Explain why the ray of light changes direction at P. (2) The student varies the angle of incidence and obtains this table of results. Angle of incidence i Angle of refraction r sin i sin r 11° 7° 0.19 0.12 24° 15° 0.41 0.26 47° 28° 0.73 0.47 65° 36° 0.91 0.59 90° 40° 1.00 0.64 (ii) Plot a graph of sin i against sin r. (4) (iii) Draw the straight line of best fit. (1) (iv) Use your graph to find the refractive index of glass. (2) (v) State the relationship between refractive index, angle of incidence and angle of refraction (1)
