Waves(Mechanical) Flashcards
all about waves
Mechanical Waves:
Mechanical waves require a medium (such as air, water, or solids) to travel through. They involve the transfer of energy from one point to another without the physical transfer of matter.
Waves
Waves are a fundamental concept in physics and can be broadly categorized into mechanical waves and electromagnetic waves.
Types of Mechanical Waves:
Transverse Waves: In transverse waves, the particles of the medium oscillate perpendicular to the direction of wave propagation. Examples include water waves and electromagnetic waves.
Longitudinal Waves: In longitudinal waves, the particles of the medium oscillate parallel to the direction of wave propagation. Examples include sound waves and seismic waves.
Properties of Mechanical Waves:
Amplitude: The maximum displacement of particles from their equilibrium position.
Wavelength (λ)
: The distance between two consecutive points in a wave that are in phase (e.g., crest to crest or trough to trough): The distance between two consecutive points in a wave that are in phase (e.g., crest to crest or trough to trough)
Frequency (𝑓)
: The number of complete oscillations (cycles) of a wave per unit time, measured in Hertz (Hz).
Period (𝑇)
: The time taken for one complete oscillation of a wave, the reciprocal of frequency. T=1/F
Wave Speed (𝑣)
: The speed at which the wave propagates through the medium, calculated as the product of wavelength and frequency
v=λx𝑓
