One image should be formed by rays that go directly through the bubble and another image is formed by reflected light that hits the bubble.
n1 = 1
n2 = 1.5
R = -7.5 CM
so = 5 cm
If n1 = n2, then si would equal 15 cm as measured from the second vertex on the concave surface. However, they're not equal and the light ray is refracted at the plane. Since n1 is less than n2, the light ray will be refracted away from the perpendicular line. Thus, si' is less than 15 cm.
How do I find an exact value for this second image? I assume the first image is also along the optical axis, but where?
