Irene (5ºA) wants to share this information with all of you:

I found information about the state of light and the state of sound. Did you know light could be in a solid state? It’s a type of lightning which uses semiconductor light-emitting diodes (OLED) or polymer light-emitting diodes (PLED) as sources of illumination on rather than electrical filaments, plasma, or gas.
What state of matter does sound travel the fastest? Solids transmit sounds fastest, and farther. The more dense the material is, the better sound could be counducted.
Temperature also affects the speed of sound.
(I know this is a little bit complicated, but I love Science!)

Thank you Irene!!! Guiño
