The video tutorial explains the concept of amplifying a sound wave in physics, which involves increasing its amplitude to enhance the volume of the sound.

What is the primary focus of amplifying a sound wave in physics?

• To decrease the speed of the sound wave

• To alter the pitch of the sound

• To increase the amplitude of the sound wave

• To change the frequency of the sound

What happens to the sound when its amplitude is increased?

• The sound becomes softer

• The sound becomes louder

• The sound becomes slower

• The sound becomes higher in pitch
