class 8 science notes

The sound wave was discovered back as far as Leonardo da Vinci’s  (1452–1519) era. He discovered that sound travels in waves. He was a brilliant scientist, artist, and thinker and contributed many discoveries in the field of science. He was a man before his time who thought up inventions and ideas that came to be built far later by other engineers and scientists.
