Why These 5 Rocks Actually Glow

The video explores various types of glowing rocks and the mechanisms behind their luminescence. It covers fluorescence, phosphorescence, triboluminescence, thermoluminescence, and electroluminescence, explaining how each process works and the conditions required for rocks to emit light. The video also highlights the potential applications of these phenomena, such as in quantum computing.

What is the primary reason fluorite glows under UV light?

• It absorbs UV light and emits it at a different frequency.

• It contains radioactive elements.

• It is heated to a high temperature.

• It reacts chemically with the air.

How does phosphorescence differ from fluorescence in rocks?

• Phosphorescent rocks glow longer after the light source is removed.

• Phosphorescence only occurs in radioactive rocks.

• Phosphorescent rocks do not require UV light to glow.

• Phosphorescence requires a chemical reaction with air.

What is a key requirement for a rock to exhibit triboluminescence?

• It must be exposed to UV light.

• It must be radioactive.

• It must have an asymmetric crystal lattice.

• It must have a symmetric crystal lattice.

Which phenomenon involves rocks glowing due to mechanical stress?

• Fluorescence

• Phosphorescence

• Triboluminescence

• Electroluminescence

What causes thermoluminescent rocks to emit light?

• Chemical reactions with air

• Heating after absorbing energy from another source

• Mechanical stress

• Exposure to UV light

How can electroluminescent rocks be identified?

• They glow when an electric current is passed through them.

• They glow when heated to high temperatures.

• They glow due to chemical reactions with air.

• They glow when exposed to UV light.

What potential application does the electroluminescence of diamonds have?

• Creating glow-in-the-dark jewelry

• Advancing quantum computing

• Developing more efficient solar panels

• Improving LED technology
