Properties of Waves
- Waves are described by amplitude, wavelength, frequency, and wave speed.
- Amplitude is the measure of how far a particle in the medium moves away from its normal position. It's half the difference between a crest and a trough.
- Wavelength is the distance from any point on a wave to an identical point on the next wave pulse (crest to crest, or trough to trough). It measures the length of one cycle of a wave.
- Frequency is the number of waves produced in a set amount of time, typically expressed in Hertz (Hz). One Hertz equals one wave per second (1 Hz = 1/s).
- Wave speed is the rate at which a wave travels; it can be calculated by multiplying wavelength and frequency (v = fλ). Units are typically m/s.
Wave Speed Calculations
- Wave speed formula: Speed (v) = frequency (f) x wavelength (λ)
- Units: Speed (m/s), Frequency (Hz), Wavelength (m)
- Example calculations are provided in the notes for various given values.
Objectives and Activities
- Objectives for Day 1 include identifying wave properties, amplitude, wavelength, and frequency. It also includes explaining relationships between energy and amplitude in waves and predicting wave speed.
- Vocabulary includes Amplitude, Wavelength, Frequency, and Wave Speed.
- Students will use a slinky to determine amplitude and frequency of a wave.
Energy and Amplitude
- The amplitude of a wave is directly related to its energy. A wave with a larger amplitude carries more energy than a wave with a smaller amplitude.
- The energy of a wave is proportional to the square of its amplitude, given the frequency and medium are held constant.
Additional Concepts
- Types of mechanical waves are to be defined in a later lesson.
- Wave Speed Calculations, formulas, examples, are provided in the notes to guide student practice.
- Types and comparisons of Longitudinal and Transverse waves are covered in a subsequent day/lesson.
- Differentiating between high and low energy waves using drawings/illustrations are discussed for the given concept.
