Sound can be produced due to vibrations.Using household materials make any one musical instrument.Student must be able to explain variation in the amplitude and frequency in the given instrument.
in this i have made a violin which does not produces sound.so how can i explain nits variation in amplitude and frequency and have i to make a instrument that can produce sound.
