Answer

Brief Explanations:

The loudness of a sound is related to the amplitude of the sound - wave. When a sound is played louder while keeping the pitch the same, the amplitude of the sound - wave increases. The speed of sound in a given medium is constant for a particular temperature and medium type, and the pitch is related to the frequency (and wavelength is related to frequency and speed by $v = f\lambda$). Since the pitch is the same, the frequency and wavelength remain the same.

Answer:

The amplitude of the sound wave will increase.
