Final answer:
The speed of light in a zircon crystal can be calculated using the provided index of refraction, 1.923, and the vacuum speed of light. By dividing the speed of light in a vacuum by the index of refraction, you can find the slowed speed of light in zircon.
Step-by-step explanation:
The question suggests a focus on the speed of light in a zircon crystal, as well as its index of refraction. The index of refraction for zircon is provided as 1.923. The equation for the speed of light (often denoted as c) when calculating how it travels through a medium is c/n, where n is the index of refraction of the medium. Since the value of c in a vacuum is approximately 299,792,458 meters per second, to find the speed of light in zircon, you would substitute the given index of refraction into the equation.
Here's the calculation: Speed of light in zircon = c / index of refraction = 299,792,458 m/s / 1.923. This calculation demonstrates the relationship between the index of refraction and the speed at which light can travel through different media, which is a fundamental concept in physics, specifically in the study of optics.
