Study Notes
Waves
- A wave is any disturbance that transfers energy from one place to another.
- A medium is a material or matter through which a wave travels.
- A vacuum is completely empty space.
- Mechanical waves require a medium to travel. Examples include sound waves.
- Electromagnetic waves do not require a medium to travel. Examples include visible light, radio waves, X-rays, and microwaves.
- Mechanical waves are classified by the direction of wave motion.
- Transverse waves: The wave motion is perpendicular to the direction of energy transfer. Examples include a wave traveling along a rope when it's moved up and down.
- Crest: The high point of a transverse wave.
- Trough: The low point of a transverse wave.
- Longitudinal waves: The wave motion is parallel to the direction of energy transfer. Examples include sound waves.
- Compression: Areas where the coils are tightly spaced together.
- Rarefaction: Areas where the coils are spread apart.
- Surface waves: A combination of transverse and longitudinal waves, moving in a circular motion. Examples include ocean waves.
- Transverse waves: The wave motion is perpendicular to the direction of energy transfer. Examples include a wave traveling along a rope when it's moved up and down.
Wave Properties
- Energy Transfer: Amount of energy transfer depends on the source of vibration of the wave.
- faster vibrations = more energy transferred.
- larger amplitudes = more energy transferred.
- Amplitude: The distance between the highest point (crest) and the resting position of a wave. Greater amplitude means greater energy.
- Wavelength: The distance a wave travels before repeating.
- Frequency: The number of complete waves passing a given point per second (measured in Hertz).
- Speed: How fast a wave travels. Speed = distance / time.
- Wave energy is proportional to the square of its amplitude.
- A wave's energy is also proportional to its frequency.
- Light travels much faster than sound.
