Question

A student holding a 324Hz tuning fork approaches a wall at a speed of 6ms^(-1). The speed of sound in air is 336ms^(-1). What frequency will the student detect from waves omitted from the fork and waves coming from the wall?​

Answer 1

The frequency the student detect from waves omitted from the fork and waves coming from the wall is 348.1 Hz.

Frequency detected by the student

The observed frequency is determined by applying Doppler effect;

f' = f₀(v + v₀)/(v)

where;

• f' is the observed frequency
• v is speed of sound
• v₀ is the source speed
• f₀ is the original frequency

f' = 342(6 + 336)/(336)

f' = 348.1 Hz

Thus, the frequency the student detect from waves omitted from the fork and waves coming from the wall is 348.1 Hz.
