Problem

In an optics experiment, a laser beam in glass (n=1.50n=1.50) enters glycerin (n=1.47n=1.47) at an incident angle of 60∘ ⁣± ⁣1∘60^{\circ}\!\pm\!1^{\circ} measured from the normal in the glass. Indices of refraction are known precisely. Which range below most accurately contains the possible values of the refracted angle in the glycerin, measured from the normal? (a) 60∘ to 61∘60^{\circ}\text{ to }61^{\circ} (b) 61∘ to 63∘61^{\circ}\text{ to }63^{\circ} (c) 58∘ to 59∘58^{\circ}\text{ to }59^{\circ} (d) 65∘ to 67∘65^{\circ}\text{ to }67^{\circ}
