Study Guide Overview
This study guide covers periodic waves, including concepts like amplitude, frequency, wavelength, speed, and energy. It explains the relationships between period, frequency, and wavelength, specifically noting the inverse relationship between frequency and wavelength when speed is constant. The Doppler Effect is also discussed, describing how relative motion between source and observer impacts observed frequency and wavelength.

#Enduring Understanding 6.B 👨💻
A periodic wave is one that repeats as a function of both time and position and can be described by its amplitude, frequency, wavelength, speed, and energy.
#Essential Knowledge 6.B.1 🏘
For a periodic wave, the period is the repeat time of the wave. The frequency is the number of repetitions of the wave per unit time.
#Essential Knowledge 6.B.2 🏘
For a periodic wave, the wavelength is the repeat distance of the wave.
#Essential Knowledge 6.B.4 🏘
For a periodic wave, wavelength is the ratio of speed ove...
