All Flashcards
Label the parts of a transverse wave: crest, trough, wavelength, and amplitude.
Crest: Highest point of wave, Trough: Lowest point of wave, Wavelength: Distance between two crests (or troughs), Amplitude: Height from equilibrium to crest (or trough).
Label the parts of a longitudinal wave: compression, rarefaction, and wavelength.
Compression: Region of high density, Rarefaction: Region of low density, Wavelength: Distance between two compressions (or rarefactions).
How do you calculate the velocity of a wave using wavelength and frequency?
Use the formula: v = λf, where v is velocity, λ is wavelength, and f is frequency.
How do you calculate the velocity of a wave using wavelength and period?
Use the formula: v = λ/T, where v is velocity, λ is wavelength, and T is the period.
What is the effect of increasing the amplitude of a wave?
Classically, the energy carried by the wave increases.
What happens to the wavelength of a wave if the frequency decreases, assuming constant velocity?
The wavelength increases.
What is required for mechanical waves to propagate?
A medium is required.
