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...
IB DP Physics: HL复习笔记4.3.5 Malus’s Law
Malus's Law Intensity of Polarised Light The intensity of unpolarised light is reduced as a result of polarisation If unpolarised light of intensity I0 passes through a polariser, the intensity of ...
IB DP Physics: HL复习笔记4.3.4 Polarisation
Polarisation Transverse waves can oscillate in any plane perpendicular to the direction of motion (and energy transfer) of the wave Such waves are said to be unpolarised When a transverse wave is p...
IB DP Physics: HL复习笔记4.3.3 Superposition
Superposition The principle of superposition states that: When two or more waves meet, the resultant displacement is the vector sum of the displacements of the individual waves The principle of su...
IB DP Physics: HL复习笔记4.3.2 Amplitude & Intensity
Amplitude & Intensity Intensity The intensity of a wave is defined as follows: Power per unit area Intensity is measured in W m–2 Power is defined as: The rate of energy transfer Therefore, in...
IB DP Physics: HL复习笔记4.3.1 Wavefronts
Wavefronts Waves can be represented graphically in two different ways: Wavefronts - lines joining all the points that oscillate in phase and are perpendicular to the direction of motion (and energy...
IB DP Physics: HL复习笔记4.2.4 Sound Waves
Sound Waves Sound waves are longitudinal waves and, as such, require a medium in which to propagate Sound waves are generated by oscillating sources, which produce a change in density of the surrou...
IB DP Physics: HL复习笔记4.2.3 Electromagnetic Waves
Electromagnetic Waves An electromagnetic wave is generated by the combined oscillation of an electric and a magnetic field These fields oscillate perpendicular to each other and to the direction of...
IB DP Physics: HL复习笔记4.2.2 Transverse & Longitudinal Waves
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 determined by the di...
