Theory & Logic
Theoretical Background
Physics describes the fundamental mechanism of the universe. The Doppler Effect (Source Moving) is an essential tool for understanding Doppler Effect (Source Moving) in quantitative terms. Calculate observed frequency (approaching).
Mathematical Formulation
The relationship between the variables is governed by the following equation:
Variable Legend
| Symbol | Parameter | Unit |
|---|---|---|
| f | Source Freq (f) | Hz |
| v | Sound Speed (v) | m/s |
| vs | Source Vel (vs) | m/s |
Practical Calculation Example
Problem
Calculating the result when:
- Source Freq (f) = 60 Hz
- Sound Speed (v) = 60 m/s
- Source Vel (vs) = 25 m/s
Solution
Substituting into Eq 1.1:
Result = 60 × (60 ÷ (60 - 60s))
