help me pls

. light is travelling within medium & and approaches the X-diamond interface at A with an After entering the diamond, the light ray approaches the water - diamond interface at B an incident If total internal reflection occurs at B, the beam of light will encounter the diamond-glass interface a G2 is the angle of incidence of the light at the diamond-glass interface at C, as well as the angle of re X-diamond interface at A. 0 Note that (2 + 03 = 90" at all times. blanks to be filled): e values of the critical angle for total internal reflection at point B and point C. These values should be calculated to exam be used at all intermediate steps (if any) up to this point. B is : 1 degrees C 15 : 2 degrees al angles at B and at C (each with exactly 3 significant figures) to calculate the minimum and the maximum value of 6, su A will reach the diamond-glass interface at C, but no light will enter the glass. t all times. 3 degrees 15 4 degrees
