Study Notes
Wave Types
- Transverse waves oscillate perpendicular to the direction of wave travel.
- Longitudinal waves oscillate parallel to the wave's direction.
- Combined waves exhibit characteristics of both transverse and longitudinal waves.
- Sound waves are a type of longitudinal wave.
Amplitude and Wavelength
- Amplitude refers to the maximum displacement from the rest position.
- Wavelength is the distance between consecutive peaks or troughs in a wave.
- Example: A wave with an amplitude of 30 cm and a wavelength of 110 cm shows specific measurements used in assessments.
Wave Properties
- Lower amplitude yields lesser energy, while higher amplitude indicates greater energy.
- A standard amplitude measurement may vary; for instance, a wave can have 15 cm amplitude with a wavelength of 150 cm.
- Understanding how to measure amplitude and wavelength is essential for wave analysis.
Frequency
- Frequency is the number of oscillations or waves that pass a fixed point within a second.
- High frequency indicates close wave cycles, while low frequency indicates more spread out cycles.
- An estimated frequency of a wave can be assessed as 2.50 Hz, illustrating a rapid oscillation.
Power of a Wave
- The power of a wave can be increased by several methods:
- Increasing amplitude raises energy transmission.
- Increasing frequency results in more wave cycles per second.
- Increasing tension on the medium (such as a spring) enhances wave propagation.
- All these methods contribute to higher wave power and stronger wave impacts.
