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...
牛津本科很多专业都要求申请者参加admissions test，也就是入学考试。 牛津本科一共有13项入学评估，除了10个统一笔试，还有美术的实践考核、音乐的表演评估，以及LNAT法律入学笔试。 而剑桥入学考试分为pre-inte...
近日，牛剑默不作声地突然“联手”搞了大事情！！ 不仅把2022年所有笔试报名截止时间都提前到了9月30日，剑桥更是把多个原计划11月2日举行的笔试，提前到了10月18-19日！ 剑桥官宣部分入学笔试提前 突如其来的提前...
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 ...
