Study Notes
Wave Characteristics
- The trough is the lowest point in a transverse wave, signaling the wave's depth.
- The crest is the high point of a transverse wave, marking its peak.
- Waves are disturbances that transfer energy from one location to another.
Types of Waves
- Longitudinal waves involve particle motion parallel to wave direction, with compressions and rarefactions.
- Compression refers to areas where particles of the medium are closely packed in a longitudinal wave.
- Rarefaction is the region in a longitudinal wave where particles are spaced far apart.
Wave Properties
- Transverse waves feature particle movement at right angles to wave travel.
- The wavelength is the distance between two consecutive crests or troughs, crucial for wave measurement.
- Frequency is quantified as the number of complete waves passing a point within a specific timeframe, typically measured in hertz (Hz).
Mechanical and Electromagnetic Waves
- Mechanical waves require a medium (material) to transfer energy, while electromagnetic waves can transfer energy through a vacuum.
- The height of a transverse wave, known as amplitude, signifies wave intensity.
Wave Behavior
- Reflection occurs when a wave bounces off a barrier, leading to the formation of incident and reflected waves.
- An incident wave strikes a barrier, while the reflected wave is the output upon bouncing from it.
- The normal is an imaginary line that is perpendicular to a barrier, essential for studying wave angles and interactions.
