Question

Doppler phenomenon is related with

• A. Pitch [Frequency]
• B. Loudness
• C. Quality
• D. Reflection

Answer 1

The correct option is A

Pitch [Frequency]

The explanation for the correct option

1. Doppler effect: When the source of the sound and the listener are in relative motion to each other, then the frequency of the sound heard by the listener is not the same as the frequency of the source.
2. This effect is called the Doppler effect. Doppler effect is related to frequency.

Hence, the correct option is $\left(A\right)$.
