The 1000 Hz tone produces a sound wave that vibrates at 1000 cycles per second. When played through the speaker, these vibrations can help dislodge small debris (like dust or dirt) that may be stuck in the tiny speaker grill. Higher-frequency sound waves, like 1000 Hz, tend to have a more rapid oscillation, which can

NOCODUSA on Instagram: "How frequency can change water flow is one of the coolest examples of physics you can actually see with your eyes. When sound waves or vibration frequencies hit water, they create pressure variations that force the water to move in repeating patterns. These vibrations push and pull the water molecules in rhythm, causing waves, ripples, standing patterns, and even shapes that look unreal. This effect is part of cymatics, a field that studies how sound influences physical m
