Metal Resonance Strips
The lowest frequency at which a metal wire resonates is called the fundamental frequency of the wire and the corresponding wavelength is called the fundamental wavelength. The speed of wave propagation (v), the frequency of oscillation (f), and the wavelength (λ) are related by the equation v = λf. A longer metal wire has a…Read More
A standing wave is called the result of the contribution of two waves of the same frequency and the same width that are propagated in the same medium with opposite directions. When two or more waves are propagated in an elastic medium, we use the principle of superposition, according to which: When two or more…Read More
Mechanical Waves Theory
A wave is created when a medium is disturbed from its equilibrium. A wave is the propagation of a disturbance from one point of a medium to another. During the propagation of a wave, energy is transferred from one region of the disturbed system to another without transferring matter. Mechanical waves are the waves which…Read More
Lets make a string phone!
Sound waves are longitudinal waves with frequency between 20 Hz and 20,000 Hz, that travel through air, solids or liquids. Materials: 2 paper cupboards 3m string Procedure: With a pencil make a small hole in the bottom of each cup and pass the end of the twine inside each cup. Tie 3 knots at the ends…Read More
