An image explaining that humans can see light frequencies from 430-790 THZ and hear sound frequencies between 20 HZ-20 KHZ. The text notes that these ranges are just a small portion of the entire spectrum of light and sound, meaning much of what exists is invisible to us. Credit: Hashem Al-ghalli/Science Nature Page.
The universe is full of secrets hidden in plain sight (or rather, plain sound and light)! We only perceive a small fraction of the electromagnetic and sound frequencies. How much more is out there? #ScienceFacts #Universe #ElectromagneticSpectrum #SoundWaves #Frequency #NatureIsAmazing #UnseenWorld
