If the light encounters the glass at an angle of 40.00 with respect to the glass,find the shift in path Ax as the light enters the room. (Use na 1.00) 40.000 Number glass 12.0 mm air 9.60 mm lass 12.0 mm

Explanation / Answer

1.00* Sin40 = 1.40* Sin r

Sin r = 0.64278761 / 1.4

r = 27.331 degree

Ls = tSin ( i - r ) / Cos r

Ls = 12 Sin ( 40 - 27.331 ) / Cos 27.331

Ls = 2.9625 mm

after crossing two glass

Net Ls = 2*2.9625 = 5.925 mm
