# Energy And Waves Quiz

13 Questions | Total Attempts: 1640  Settings  Waves can transfer energy through a distance without moving matter the entire range. When it comes to an understanding the relationship between energy and waves, you must know that the greater the energy, the larger the frequency and the shorter the wavelength. Take this energy and waves quiz on the 8th-grade level and get to understand just how much you understood about the topic. All the best!
