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:

Result = f × (v ÷ (v - vs))
Eq 1.1: Governing Formula

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))
