A student observes a pencil half-immersed in water (refractive index 1.33) and notices the apparent bending is less than when the pencil is in a liquid with refractive index 1.5. What does this suggest about the relationship between refractive index and light bending?
Greater refractive index increases bending
Refractive index measures how much a medium slows light and bends it at the boundary.
The pencil looks less bent in water (1.33) than in the liquid of refractive index 1.5, so the medium with the higher refractive index bends light more.
Hence, the answer is that a greater refractive index increases bending.
