Required Practical: Investigating Stationary Waves Aims of the Experiment The overall aim of the experiment is to measure how the frequency of the first harmonic is affected by changing one ...
Harmonics Stationary waves can have different wave patterns, known as?harmonics These depend on the?frequency?of the vibration and the?situation?in which they are created These harmon...
Formation of Stationary Waves The Principle of Superposition The principle of superposition states: When two or more waves with the same frequency arrive at a point, the resultant displaceme...
Polarisation Polarisation is when: Particle oscillations occur in only one of the directions perpendicular to the direction of wave propagation Polarisation can only occur in transverse wave...
Defining Transverse & Longitudinal Waves In mechanical waves, particles?oscillate?about fixed points There are two types of wave:?transverse?and?longitudinal The type of wave can be dete...
Analysis of the Nature of Matter The Evolving Field of Quantum Mechanics The field of quantum mechanics is a relatively new field of research, compared to fields in classical mechanics (Newt...
Diffraction Effects of Momentum When electrons pass through a slit similar in size to themselves, they exhibit a wavelike property(?Diffraction), meaning they spread out like a wave passing ...
The de Broglie Wavelength Using ideas based upon the quantum theory and Einstein’s theory of relativity, de Broglie suggested that the?momentum?(p) of a particle and its associated wavelengt...
Wave-Particle Duality Light can behave as a particle (i.e. photons)?and?a wave This phenomenon is called the wave-particle nature of light or?wave-particle duality Light interacts with matte...
