- Lesson Plan →Objectives, pacing and practice, built from this lesson's brief.
- Guided Notes →One page your students fill in and keep.
- Exit Ticket →Three items at the end of class. No student accounts.
- Re-teach →After an exit ticket: who missed what, and what to do tomorrow.
- Homework →Assign practice; it grades itself.
"The Doppler effect is a change in the observed pitch of a sound, due to relative motion between the source and the observer."
"For a stationary observer and a moving source of sound, the frequency (*f*<sub>obs</sub>) of sound perceived by the observer is $f_{obs} = f_s\left(\frac{v_w}{v_w \pm v_s}\right)$ ... The minus sign is used for motion toward the observer and the plus sign for motion away from the observer."
"A sonic boom is a constructive interference of sound created by an object moving faster than sound."

What you'll learn
- Describe the Doppler effect and explain why it occurs in terms of wavefronts and relative motion
- Apply the Doppler shift formula for a moving source to find the observed frequency
- Apply the Doppler shift formula for a moving observer, choosing the correct sign
- Explain how a sonic boom forms as a source approaches and exceeds the speed of sound
- Recognize that the Doppler effect occurs for all waves, not only sound
