The critical angle for a water to air interface is 48.6º. When light passes from air into water at a 50º angle, the wave will
Completely reflect into air
Completely reflect into water
Bend closer to normal
Bend further from normal
Which one is it? I am in this online class thing, and they teach you everything, and normally I do very well, but this critical angle stuff is unclear to me, as nobody ever taught it to me. I have many more questions about this topic, so if somebody wants to just put a full explanation about it, I'd be very thankful.
