The Fascinating Relationship Between Vibrations and Waves

🌊Waves and vibrations are closely related but have distinct differences. Vibrations involve back-and-forth motion, while waves involve the transfer of energy through a medium.

🔄In the experiment with a long spring steel tape, vibrations were demonstrated by holding one rod firm and making another rod vibrate. Waves were demonstrated by displacing one rod, causing a wave to travel along the tape.

🔁When two sets of waves with the same amplitude and wavelength but moving in opposite directions meet, they create standing vibrations with nodes and loops.

🌙Resonance occurs when a vibrating object is subjected to a series of pushes at its natural frequency, resulting in a large amplitude vibration.

📈Wave velocity, wavelength, and frequency are interrelated. Higher frequency waves have shorter wavelengths, and vice versa. Velocity is the product of frequency and wavelength.
