nwater sin thetawater
= nair sin thetaair (Snell's Law)
nair is slightly greater than nvacuum
thus its value is slightly larger than one. All other mediums
will have larger indexs of refraction.
There is an inverse relationship between the
index of refraction and the angle. Air has the lower index of
refraction and the larger angle.
Because the angle is less than the critical
angle, total internal reflection will not occur.
The Correct Answer is B.
