Answer» Answer: begin mathsize 12px style Angle SPACE of space incidence space is space straight i equals 45 degree Angle space of space refraction space is space straight r equals 30 degree left PARENTHESIS straight i right parenthesis space REFRACTIVE space index space of space second space medium space straight w. straight r. straight t space first space medium space is straight mu presubscript 1 subscript 2 equals sini over sinr equals FRACTION numerator sin 45 over denominator sin 30 end fraction equals fraction numerator begin display style bevelled fraction numerator 1 over denominator square root of 2 end fraction end style over denominator begin display style bevelled 1 half end style end fraction equals fraction numerator 2 over denominator square root of 2 end fraction equals 1.41 left parenthesis ii right parenthesis space Refractive space index space of space first space medium space straight w. straight r. straight t space second space medium space is straight mu presubscript 2 subscript 1 equals fraction numerator 1 over denominator straight mu presubscript 1 subscript 2 end fraction equals fraction numerator 1 over denominator 1.41 end fraction equals 0.707 end style |
