Here's the solution for question 8. (a) (ii): To complete the table, we need to calculate the sine of the given angles of incidence (I) and refraction (R). We will use a calculator and round the values to three decimal places for consistency. Step 1: Calculate the missing values for I. For I = 30^: (30^) = 0.500 For I = 40^: (40^) ≈ 0.643 For I = 60^: (60^) ≈ 0.866 For I = 80^: (80^) ≈ 0.985 Step 2: Calculate the missing values for R. For R = 19^: (19^) ≈ 0.326 For R = 30^: (30^) = 0.500 For R = 35^: (35^) ≈ 0.574 For R = 41^: (41^) ≈ 0.656 The completed table is shown below: |c|c|c|c|c|c|c| I & 20 & 30 & 40 & 50 & 60 & 80 \\ R & 13 & 19 & 25 & 30 & 35 & 41 \\ Sin I & 0.34 & 0.500 & 0.643 & 0.75 & 0.866 & 0.985 \\ Sin r & 0.222 & 0.326 & 0.50 & 0.500 & 0.574 & 0.656 \\ That's 2 down. 3 left today — send the next one.
