School of Rock: The Physics of Waves on Guitar Strings
The rubber band example does indeed have two nodes—they are at the ends of the rubber band where your fingers hold it. We only have half a wavelength in the standing wave, but there is indeed a relationship between the length of the rubber band and the size of the wavelength. Guitar Strings It’s time…
Ocean heat waves often lurk out of sight
Heat waves don’t just strike on land — they can also occur in the ocean. And roughly a third of marine heat waves aren’t detectable at the ocean’s surface, a new study reports. The findings, published in the December Nature Geoscience, suggest that far more of these potentially harmful events might be occurring than previously…
