NettetAnd so the important thing to realize is that energy is flowing, light from the Sun comes in, it's slow, you know all this action goes on, and then it gets released as heat on almost every step, but the matter itself, it's always been there. All of the atoms in our body, on Earth, it's just constantly being recycled. Nettet31. mar. 2024 · Types of Waves. Waves • A wave is a back and forth motion that carries energy through matter or through space. Characteristics of a Wave • The highest points on a wave are called crests. • The lowest points are called troughs. Characteristics of a Wave • Wavelength is the distance between one crest or trough to the next. NettetSound is what happens when you transmit vibrations of energy through that matter. Sound is made up of wave vibrations. When you talk aloud, the motion of your vocal cords causes the air to vibrate ... kingstone usb c hdmi cable
