A wave is traveling through air at an angle of 75° before it enters an eye lens cover. If air has an index of refraction of 1.00, and an eye lens cover has an index of refraction of 1.38, at what angle is the wave traveling once it enters the eye lens cover?

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
