Why Do We Need To Know About Wave
Learning about waves helps us understand nature and technology better. For example, knowing about waves helps predict earthquakes, which can save lives and homes. In the music world, understanding sound waves means we can make music louder and clearer at concerts.
Also, learning about waves is key in designing quieter rooms and in studying how animals like dolphins use sound to communicate, which is part of marine biology. These examples show how wave knowledge is used everywhere, making our lives better and helping us make new discoveries.
