Study Notes
Wave Characteristics
- The defining characteristic of transverse waves is that the particles of the medium oscillate perpendicular to the direction of the wave propagation.
- Christiaan Huygens made significant contributions to the concept of waves.
Longitudinal Waves
- The characteristic that defines longitudinal waves is that the particles of the medium oscillate back and forth along the direction of the wave propagation.
Wave Measurements
- Frequency measures the number of oscillations or cycles of a wave per second.
- Amplitude measures the maximum displacement of a wave from its equilibrium position.
Wave Interference
- Constructive interference occurs when two or more waves superpose to form a resultant wave of greater amplitude.
- The phenomenon of waves combining to either add together or cancel each other out is called interference.
Wave Reflection
- The phenomenon of a wave bouncing back after encountering a barrier is called reflection.
- The bending of waves as they pass from one medium into another where their speed is different is called refraction.
Sonar Technology
- Sonar technology uses sound wave reflection to determine the distance to an object underwater.
Light Refraction
- The bending of light as it passes from one medium into another where its speed is different causes a straw to look bent in a glass of water.
Principles of Interference
- The principle behind technologies like noise-canceling headphones and holography is the concept of interference.
- The principle of interference explains why noise-canceling headphones reduce unwanted ambient sounds by combining waves to cancel each other out.
- Noise-canceling headphones use destructive interference to reduce unwanted ambient sounds.
Sound Reflection
- The significance of the nature of the reflecting surface is important in relation to sound reflection, as it affects the quality of the reflected sound.
- The significance of reflection in optimizing sound distribution is evident in the architectural context of concert halls and auditoriums.
Impedance Mismatch
- Impedance mismatch explains the phenomenon of sound reflection and refraction at the boundary of two media with different acoustic impedances.
Law of Reflection
- The principle of the law of reflection elaborates on the equality of angles in sound reflection, stating that the angle of incidence is equal to the angle of reflection.
