The completion time for multiplication in Braun or Baugh-wooley is proportional to 2n where as completion time in Wallace tree method is proportional to log(base 2)(n).

For a critical angle of 60 degree and the refractive index of the first medium is 1.732, the refractive index of the second medium is
  • a)
    1
  • b)
    1.5
  • c)
    2
  • d)
    1.66
Correct answer is option 'B'. Can you explain this answer?

Answer: b
Explanation: From the definition of Snell law, sin θc = n2/n1. To get n2, put n1 = 1.732 and θc = 60. Thus we get sin 60 = n2/1.732 and n2 = 1.5.
