Light Water

Is there an agle at which light rays in air meeting the air-water boundary will totally reflect?

Upward rays of light in water toward the water-air boundary at angles greater than 48⁰ to the normal are totally reflected. No rays beyond 48⁰ refract outside. How about the reverse? Is there an angle at which light rays in air meeting the air-water boundary will totally reflect? Or will some light be refracted at all angles?

Snells Law says n1*sin(theta1) = n2*sin(theta2).
The index of refraction of air is about 1 and the index of refraction of water is about 1.33. To be totally reflected the angle of refraction must be more than 90 degrees.

Hence 1*sin(theta1) = 1.33*sin(90) = 1.33*1 = 1.33
no angle will have a sin greater than 1. Hence light coming in at any angle will be refracted greater than 90 degrees so light will not be totally internally reflected going from air to water -- total internal refraction only can occur when coming for a higher index of refraction to a lower one.
