What kind of light can tame monsters?

About Light
Scientifically, light is a stream of photons within a specific frequency range. A light source emits light when electrons gain extra energy. If the energy is insufficient for electrons to jump to outer orbits, they accelerate and release energy in the form of waves. If the transition fills an orbital vacancy, electrons reach a stable state and stop transitioning. Otherwise, they fall back and release energy as waves.
About Spectrum
A spectrum is a pattern in which polychromatic light is separated by dispersion systems (such as prisms or gratings) into monochromatic beams arranged by wavelength (or frequency). The largest part of the optical spectrum is the visible spectrum, detectable by the human eye. However, colors like Himalayan Gray and Siberian Blue do not exist in the spectrum—they are only perceived by the visual cortex of the brain.
About Optical Filters
Since light is an electromagnetic wave of a specific frequency band, similar to radio tuning, we can select visible light in targeted bands. Optical filters are designed to absorb, reflect, or transmit specific wavelengths.
Filters are made of plastic or glass with special dyes or coatings. Untreated glass transmits almost all light, appearing transparent. After dyeing or coating, its molecular structure and refractive index change, blocking certain wavelengths. For example, white light passing through a blue filter emits only blue light, while most green and red light is absorbed.
About Fluorescence
Fluorescence is a photoluminescent phenomenon. When a material is illuminated by light of a specific wavelength, it absorbs energy, enters an excited state, and emits light at a longer wavelength (usually visible). The glow stops immediately once the excitation light is removed. Fluorescent lamps work this way: phosphors absorb UV light from mercury vapor and emit visible light.
Rocgene demonstrates the power of light
