IB DP Physics: HL复习笔记4.5.2 Nodes & Antinodes
Nodes & Antinodes A standing wave is made up nodes and antinodes Nodes are locations of zero amplitude and they are separated by half a wavelength (λ/2) Antinodes are locations of maximum ampli...
IB DP Physics: HL复习笔记4.5.1 The Nature of Standing Waves
The Nature of Standing Waves Standing waves are produced by the amplitude travelling in opposite directions This is usually achieved when a travelling wave superimposes its reflection The superposi...
IB DP Physics: HL复习笔记4.4.7 Double-Slit Equation
Double-Slit Equation Interference Patterns Interference patterns depend on: The coherent light incident on the slits The distance between the slits and the screen where the interference pattern is ...
IB DP Physics: HL复习笔记4.4.6 Interference & Path Difference
Double-Slit Interference Interference occurs whenever two or more waves combine to produce a resultant wave with a new resultant displacement The waves combine according to the principle of superpo...
IB DP Physics: HL复习笔记4.4.5 Single-Slit Diffraction
Single-Slit Diffraction Diffraction is the spreading out of waves when they pass an obstruction This obstruction is typically a narrow slit known as an aperture As waves pass through the aperture, ...
IB DP Physics: HL复习笔记4.4.4 Determining Refractive Index
Determining Refractive Index Aim of the Experiment To investigate the refraction of light by a perspex block Equipment Ray Box - to provide a narrow beam of light to refract through the perspex box...
IB DP Physics: HL复习笔记4.4.3 Refraction
Refraction When light crosses the boundary between two media with different optical densities, it refracts At the boundary, the light undergoes a change in direction The change in direction depends...
IB DP Physics: HL复习笔记4.4.2 Reflection
Reflection When light hits a smooth plane surface, most of it gets reflected Very smooth reflective surfaces (e.g. mirrors) are known as specular plane reflectors For these surfaces, the law of ref...
IB DP Physics: HL复习笔记4.4.1 Reflection, Refraction & Transmission
Reflection, Refraction & Transmission When waves arrive at a boundary between two materials, they can be: Reflected Refracted Transmitted Absorbed Reflection Reflection occurs when: A wave hits...
