**Question:** A piece of glass has an index of refraction of 1.61. What is the speed of light through the glass in m/s? **Answer:** [__________] **Explanation:** To find the speed of light in the glass, use the formula: \[ \text{Speed of light in material} = \frac{\text{Speed of light in vacuum}}{\text{Index of refraction}} \] Where: - Speed of light in vacuum = \( 3.00 \times 10^8 \) m/s - Index of refraction of glass = 1.61 Substitute the given values into the formula: \[ \text{Speed of light in glass} = \frac{3.00 \times 10^8 \text{ m/s}}{1.61} \] \[ \text{Speed of light in glass} \approx 1.86 \times 10^8 \text{ m/s} \] Enter the calculated speed of light in the answer box.
