# Doppler Effect: Source Velocity's Impact on Frequency Shift

Chapter 13, Problem 51P

(choose chapter or problem)

QUESTION:

(a) Compare the shift in frequency if a $$2000\ Hz$$ source is moving toward you at $$15 \frac{\mathrm{m}}{\mathrm{s}}$$, versus you moving toward it at $$15 \frac{\mathrm{m}}{\mathrm{s}}$$. Are the two frequencies exactly the same? Are they close?

(b) Repeat the calculation for $$150 \frac{\mathrm{m}}{\mathrm{s}}$$ and then again

(c) for $$300 \frac{\mathrm{m}}{\mathrm{s}}$$. What can you conclude about the asymmetry of the Doppler formulas?

Step 1 of 4

The following are given by the question:

Source frequency, $$f_{s}=2000 \mathrm{~Hz}$$

Source velocity, $$v_{s}=15 \frac{\mathrm{m}}{\mathrm{s}}$$

Speed of sound, $$v=343 \frac{\mathrm{m}}{\mathrm{s}}$$
