Question

lasers are pointed at different containers filled with water, oil, and air. the speed of the laser changes based on the container. what explanation best accounts for this observation? the temperature of the materials solely affects the speed of light light waves move at different speeds through different materials light waves move at the same speed in all materials the color of the containers alters the speed of light

Explanation:

Step1: Analyze each option

• Option 1: Temperature is not the sole factor affecting light speed here. The main factor is the medium (water, oil, air).
• Option 2: Light waves do move at different speeds through different materials (like water, oil, air). This is a fundamental property of light - wave interaction with media.
• Option 3: Light does not move at the same speed in all materials. For example, light moves faster in air than in water.
• Option 4: The color of the containers is not relevant to the change in the speed of light. The medium (water, oil, air) inside the containers is what matters.

Answer:

Light waves move at different speeds through different materials.
