The answer is atrial depolarization. The P wave of a normal electrocardiogram specifies atrial depolarization. In addition, depolarization happens in the four compartments of the heart which is both atria first and in both ventricles. The sinoatrial or as called as SA node on the wall of the right atrium starts depolarization in the right and left atria that can cause the contraction in which it is symbolized by the P wave on an electrocardiogram.

Answer:
The G-note's wavelength is longer.
Explanation:
As we know that
The relationship between frequency, wavelength and the speed given as
Speed = Frequency x Wavelength
V= f λ
For constant speed, if wavelength increase then the frequency of the sound get reduce.
The wavelength of the A-note sound waves is smaller than the G -notes sound waves.
Therefore the answer of the given question will be A.
