Question

light waves travel at different speeds through different media. which list shows the correct order of increasing speed of light waves, from slowest to fastest? gases → solids → liquids gases → liquids → solids liquids → solids → gases solids → liquids → gases

Explanation:

Step1: Recall the property of light speed in different media

The speed of light in a medium is inversely related to the refractive index of the medium. The refractive index of solids is generally greater than that of liquids, and the refractive index of liquids is generally greater than that of gases.

Step2: Determine the order of light speed

Since the higher the refractive index, the slower the light speed. So the order of increasing light speed (from slowest to fastest) is solids → liquids → gases.

Answer:

solids → liquids → gases
