Critical angle of glass and air
WebSo this right here, so our critical angle is 48.8 degrees So this right here is 48.8 degrees which tells us if we have light leaving water at an incident angle of more than 48.8 degrees it actually won't even be able to refract; it won't be able to escape into the air It's actually going to reflect at that boundary If you have angles less than ... WebCritical angle of a medium is the angle of incidence which causes grazing refracted ray when it passes from denser medium i.e. So μ 1 sin c = μ 2 sin 9 0 0 Hence for a glass …
