Lesson 1429 of 1524
Waves
Wave velocity and wavelength are related to the wave’s frequency and period by v = λ T = λ f
Practice this chapterWave velocity and wavelength are related to the wave’s frequency and period by v = λ T = λ f Mechanical waves are disturbances that move through a medium and are governed by Newton’s laws
A transverse wave has a disturbance perpendicular to the wave’s direction of propagation, whereas a longitudinal wave has a disturbance parallel to its direction of propagation A wave is a disturbance that moves from the point of origin with a wave velocity v
wave — disturbance that moves from its source and carries energy. transverse wave — wave in which the disturbance is perpendicular to the direction of propagation. longitudinal wave — wave in which the disturbance is parallel to the direction of propagation. mechanical wave — wave that is governed by Newton’s laws and requires a medium.
Worked example
What does “wave” mean in Waves?
- 1Use the wording this chapter gives for wave.
- 2The book says: disturbance that moves from its source and carries energy.
- 3Do not use the meaning of transverse wave. That term means wave in which the disturbance is perpendicular to the direction of propagation.
Result: disturbance that moves from its source and carries energy
Why. That is the meaning this chapter gives for wave.
Do not swap wave and transverse wave. wave means disturbance that moves from its source and carries energy. transverse wave means wave in which the disturbance is perpendicular to the direction of propagation.
