Q22DQ - University Physics with Modern Physics

Question

In case 1, a source of sound approaches a stationary observer at speed u. In case 2, the observer moves toward the stationary source at the same speed u. If the source is always producing the same frequency sound, will the observer hear the same frequency in both cases, since the relative speed is the same each time? Why or why not?

Step-by-Step Solution

Answer

The observer will not hear the same frequency in both circumstances because $f_o$  in the first case does not equal $f_o$ in the second.

Step 1: Understand the question

The question asks: In case 1, a source of sound approaches a stationary observer at speed u. In case 2, the observer moves toward the stationary source at the same speed u. If the source is always producing the same frequency sound, will the observer hear the same frequency in both cases, since the relative speed is t

Step 2: Apply Physics knowledge

Using fundamental Physics concepts to analyze the problem.

Step 3: Formulate the answer

The observer will not hear the same frequency in both circumstances because f o in the first case does not equal f o in the second.

Step 4: Conclude

The answer is: The observer will not hear the same frequency in both circumstances because f o in the first case does not equal f o in the second.
