A fiber optic cable is made of a material with index of refraction 1.55. A light ray inside the fiber optic cable approaches the surface of the fiber optic (the interface with the surrounding medium) at an angle of incidence of 58.0.

a) If the surrounding medium is air, does the light ray refract across the interface into the air? Circle yes or no and show work to support your claim.

yes / no

b) If the fiber optic is immersed in water instead of air, does the light ray refract across the interface into the water? Circle yes or no and show work to support your claim.

yes / no
