The drawing shows four different situations in which a light ray is traveling from one medium into another. In some of the cases, the refraction is not shown correctly. For cases (a), (b), and (c), the angle of incidence is 42°; for case (d), the angle of incidence is 0°. Determine the angle of refraction in each case.

Image won't show up in question so I added the information from it below

image a (n1= 1.4, n2= 1.6)

image b (n1= 1.5, n2= 1.6)

image c (n1= 1.6, n2= 1.4)

image d (n1= 1.6, n2= 1.4)

    Imagine a light ray traveling from a vacuum (medium 1) into another medium containing an unknown substance (medium 2). When the light hits the interface between the two media, the initial angle of incidence is 40 degrees (measured from a line perpendicular to the boundary surface), and it is then refracted by an angle of 29 degrees (again, measured relative to a line perpendicular to the boundary surface). What is the speed of light (in units of meters per second)...
