Period Motion Any motion that repeats at regular time intervals Frequency Number of complete cycles in a given time Frequency is measured in Hertz Hz Properties of Mechanical Waves. Waves. Ch. 20 Sec. . 1 & 2. The Nature of . Waves & Properties of Waves. Waves. We often associate waves with bodies of water, but are there other situations where waves can exist?. Waves. wave. . Bellringer. : What is A wave? (define, use Ch.22 in your book to help you). What is an example of a wave?. General definitions of vibrations and waves. Vibration. : in a general sense, anything that switches back and forth, to and fro, side to side, in and out, off and on, loud and soft, or up and down is . Doppler Effect. ~apparent change in frequency of a wave due to the motion of the source of the wave.. If the object is moving towards the observer the frequency will appear to increase. If the object is moving away from the observer the frequency will appear to decrease. The quick review. Properties shared by All Matter. Mass. Volume. Density. Know what these are!. Matter in Different Materials Can Have Different Properties. characteristics it possesses by itself . (in and of itself). S8P4b. Describe how the behavior of light waves is manipulated causing reflection, refraction, diffraction, and absorption.. Reflection. Reflection occurs when a wave strikes an object or surface and bounces off.. Energy. Wave. Amplitude. Conduction. Convection. Radiation. Color spectrum. Wavelength. Potential energy. Kinetic energy. Light energy. Chemical energy. Mechanical energy. What is Energy?. “Energy” is defined as the ability to do work. Why are we able to see?. Answer: . Because there is light.. And…what is light?. Answer: . Light is a wave.. So…what is a wave?. Answer: . A wave is a disturbance that carries energy from place to place. . Mechanical Waves. A mechanical wave is created when a source of energy causes a vibration to travel through a medium.. A mechanical wave is a disturbance in matter that carries energy from one place to another.. difference between mechanical waves and electromagnetic waves. . What is a wave?. A wave is a moving disturbance that transfers energy through matter or space. . Examples of waves. Water waves light waves. a. Identify the characteristics of electromagnetic and mechanical waves. . What are waves?. Waves carry energy. Rhythmic disturbances that carry energy without carrying matter are called waves.. Models of Waves. 2022-2023 Season. Russ Burleson. geaux15@hotmail.com. . 1.

China-Lutong, a Chinese diesel parts producer, was established in 1982 as China-Lutong Machinery Works Company Limited. The firm initially manufactured fuel injection parts for diesel engines. China-Lutong is one of the chief suppliers of diesel fuel system components in China. Energy is moving, not water. orbital motion. energy is transferred via circular motions. water (and gull) return to original position. the wave form moves forward. Motion decreases with depth. At. a depth of ½ of the wavelength, the motion is not significant.. Earthquakes-Tsunamis. Graviational. attraction-Tides. Wind waves move energy, not matter. Wind waves- Growth. Wind strength- must be moving faster than waves. Wind duration-longer creates larger waves.
