Step-by-step explanation:
Using Snell’s law ( n1 sin θi = n2 sin θr ) at point A gives
1) sin i1 = n sin r1
2) i1 = n r1
3) i1 = α1 + β1
4) r1 = β1 - γ
5) α1 + β1 = n(β1 - γ)
6) sin i2 = n sin r2
7) i2 = n r2
8) i2 = α2 + β2
9) r2 = β2 + γ
10) α2 + β2 = n(β2 + γ)
11) α1 + α2 = (n - 1)(β1 + β2)
12) 1/s + 1/s' = (n - 1)(1/R1 + 1/R2)
13) 1/f = (n - 1)(1/R1 - 1/R2)
14) 1/s + 1/s' = 1/f
