Presentation transcript:

Transverse and Longitudinal Waves Physics Learning Targets: Wave Mechanics Transverse and Longitudinal Waves Wave Characteristics Wave Behavior I can compare properties and behaviors of transverse waves and longitudinal waves, including electromagnetic waves and sound waves. This means that I can… Compare and contrast how longitudinal and transverse waves travel and move the medium that they travel in with respect to the direction of wave travel. Explain the difference between a mechanical wave and an EM wave, particularly which requires a physical medium and which one does not. Identify types of longitudinal and transverse waves (including sound, EM waves, waves on a string, water waves). State which types of waves (longitudinal/transverse) can travel through solids and which can travel through solids, liquids, and gases. Explain the real-world difference between P and S waves in seismology based on their speeds, their wave type, and their destructive power. Sketch examples of both of these waves. When did we do this? Guided Notes: Types of Waves Earthquake Project Quiz 4.1 Homework The beginning of time I can analyze characteristics of waves, including velocity, frequency, amplitude, and wavelength, and calculate them using the wave equation. State the definition of a wave. Explain the definitions of wavelength, frequency, period, and amplitude. Identify parts of a wave including crests, troughs, wavelength, compressions, rarefactions, and amplitude. Apply the wave equation to solve for wavelength, frequency, or speed of a wave. Calculate period from frequency, or vice versa. Interpret a graph of a wave’s position and time to find its period. Calculate the relative energies of two waves given their amplitudes Green foldable Earthquake project In-Class Problems I can explain and investigate the behaviors of waves, including reflection, refraction, diffraction, and interference. This means that I can…. Define reflection, refraction, and diffraction Identify visual representations of refraction, diffraction, reflection, and interference Explain what it means for waves to add constructively and destructively Predict the direction of a light wave bending from the 3 conditions of refraction Apply the diffraction condition to determine when interference is produced Sketch the resulting wave in a graph when two waves interfere Use the law of reflection to predict angles of incidence or reflection *Standing waves will not be tested in this exam.* Blue Foldable In-Class Simulation Standing Waves and Interferences Notes + Reading

Possible Free-Response Topics Sketching and labeling respective parts of a longitudinal or transverse wave. Solving a beat frequency problem and explaining solution. Sketching the result of two waves interfering. Compare/contrast refraction, reflection, and diffraction. Given two waves, calculate ratios of energy from amplitudes. Reading a graph like the earthquake project and identifying period, solving for frequency, etc.
