Light is fastest in air, followed by glass, and then diamond. The speed of light in a medium is determined by its refractive index, which is a measure of how much the speed of light is reduced in that medium compared to its speed in a vacuum. Air has a refractive index close to 1, glass has a higher refractive index, and diamond has the highest refractive index among the three materials. **

No, armored glass cannot be destroyed with a diamond. Armored glass is designed to be highly resistant to impact and penetration, including from sharp objects like diamonds. Diamonds are not hard enough to scratch or shatter armored glass, which is typically made from multiple layers of glass and plastic that are specifically engineered to withstand high levels of force and pressure. **

Overall, spiritual teachers can have a multifaceted impact on our lives, not just in uplifting us, but also in guiding, supporting, and challenging us. **

Yes, light travels at different speeds in different materials. In general, light travels slower in glass than in a vacuum, with a speed of about 200,000 kilometers per second. In diamond, light travels even slower, at around 125,000 kilometers per second. This difference in speed is due to the interaction of light with the atoms in the material, which affects its propagation. **
