Water bends light. This type of bending is called refraction. The drawing tool shows a penny submerged in water, but only part of the path of the light ray is shown. How could the light ray bend as it enters and leaves the water so that you can see the penny at position B? Draw the missing parts of the light ray so the penny is visible at position B.
