Unformatted text preview: The index of refraction of the water is 4/3. a) 0.537 m; b) 0.374 m; c) 0.753 m; d) 0.626 m; e) 0.109 m. Problem 24 (like 25.23): A researcher wishes to illuminate a bacterial cell on the other side of an acrylic plate simultaneously with two narrow laser beams in air ( n 1 =1.000). If the 400 nm beam ( n 2 = 1.507) is at an angle of 30 o relative to the normal to the surface, what must be the angle of the 600 nm beam ( n 2 ’ = 1.490) so that both beams go in the same directi on? a) 30.00 o ; b) 30.86 o ; c) 29.63 o ; d) 30.38 o ; e) 28.25 o ....
