Question

q2 exam practice - fl.sc.7.p.10.2 - reflection, refraction and absorption
a student places a flashlight behind a clear ice cube and observes that the light bends slightly as it passes through.
which statement best explains this observation?
the light is absorbed by the ice cube and re - emitted.
the light is refracted as it changes speed moving through the ice.
the ice cube scatters the light in all directions.
the ice cube reflects all light that hits it.

Explanation:

The observation of light bending when passing through the ice cube is explained by refraction. Refraction occurs when light changes speed as it moves from one medium (air) to another (ice), causing its path to bend. Absorption and re-emission would not directly cause bending, scattering spreads light in all directions (not just slight bending), and reflection bounces light back (not through the cube).

Answer:

The light is refracted as it changes speed moving through the ice.
