3. Doppler Effect 10.3 What is the doppler effect?
Doppler effect: an observed change in pitch when either the  sound source or the listener is in motion.
2. When an object is close to you it has less of a distance to travel. The frequency is higher because more waves reach you.
When the object is far away it has more of a distance to travel, so the frequency is lower as less waves reach you.
High frequency = high pitch
Low frequency = low pitch
What is the doppler effect?
2) Why does the pitch sound like it’s changing?

4. Mini lab questions
1. The doppler effect is _________________ ____________________________________ 2. When the object is closer to you the pitch is _____________ (higher/lower) because __________________________________ 3. When the object is far away from you the pitch is _____________ (higher/lower) because ___________________________ 4. When I put the tuning fork in water, the fork _______________________________
