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.
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.
Compare and contrast transverse and longitudinal waves.
Transverse: Particles oscillate perpendicular to wave direction; examples include light waves. Longitudinal: Particles oscillate parallel to wave direction; examples include sound waves. Both transfer energy.
Compare the relationship between amplitude and energy in waves.
Higher amplitude: Carries more energy. Lower amplitude: Carries less energy.
