Waves Flashcards
Wave Equation
v = fƛ
Types of Waves
Transverse & Longitudinal
What is a Transverse wave
a wave that oscillates perpendicular to the direction the wave is travelling
Wavelength in a Transverse Wave
Distance between two peaks or troughs
Amplitude
The maximum displacement of particles away from the rest position
Frequency
number of waves created in a second
Wavelength in longitudinal waves
distance between two compressions or rarefaction
Examples of Transverse Waves
Light, Radio, Water, Infra Red, S waves
Examples of Longitudinal waves
sound, ultrasound, p waves
Human Hearing Range
20-20,000 Hz
pitch depends on …
Frequency
Loudness depends on …
Amplitude
Resonance is when…
the frequency of the driving force matches the natural frequency of an object which increases amplitude
Damping is…
caused by a resistive force lowering the amplitude
wavefront
the front of the wave or the same point on each wave
