Waves Sound And Light Study Guide Answers
Waves, Sound, and Light Study Guide Index Introduction Types of Waves Properties of Waves Problem Solving Behavior of Waves Sources Introduction So waves are everywhere. But what different properties make up a wave? What characteristics, properties, or behaviors are shared that we typically characterize as being a wave? How can waves be described in a manner that allows us to understand their basic nature and qualities? Types of Waves Transverse Waves Compressional/Longitudinal Waves Surface Waves Introduction Cont.
What all makes up a wave? The types of waves, properties of waves and the behavior of waves. Longitudinal Waves Longitudinal waves is a wave in which the vibration of the medium is parallel to the direction the wave travels. When the particles in a medium are close its a compression. When the particles in a medium are spaced its a rarefaction.

Examples: A spring being pushed parallel, back and forth. P waves 'primary waves' happens when an earthquake occurs. Transverse Waves Transverse waves cause the medium to vibrate at right angles to the direction in which the wave travels. The highest point in a wave is called a crest. The lowest point in a wave is called a trough.

Examples: When you shake one end of a rope up and down, the vibration causes a wave. A yo-yo vibrates up and down between maximum and minimum height. Shaking one end of a blanket up and down sends transverse waves through the blanket.
By: Danaya Jackson Due: April 18th Surface Waves Surface Waves is a wave that travels along a surface seperating two media. Examples: A fishing bobber floating in the ocean. Propeties of Waves Diagrams Problem Solving Wave Speed Equation Solving for Speed 1.
One end of a rope is vibrated to produce a wave with a wavelength of 0.25 meters. The frequency of the wave is 3.0 hertz. What is the speed of the wave? Behavior of Waves Reflection Solving for Wavelength 2. What is the wavelength of an earthquake wave if it has a speed of 5 km/s and a frequency of 10 Hz? Solving for Frequency 3.
Sound And Light Waves
Frequency of a wave is 250 Hz. What is its time period? Diffraction Diffraction is the bending of a wave as it moves around an obstacle or passes through a narrow opening. Constructive Interference Occurs when two or more waves combine to produce a wave with a larger displacement.
Sources Frequency is measured in cycles per second or hertz (Hz). Frequency is the number of wave cycles that pass a point in a given time. The time required for one cycle, a complete motion that returns to its starting point is a period. Wavelength is the distance between a point on one wave and the same point in the next cycle of the wave. Amplitude of a wave is the maximum displacement of the medium from its rest postion. Amplitude, Wavelength & Period Diagram Speed = Wavelength X Frequency 1Htz = 1/s Speed = 0.25 X 3.0 Hz which = 0.25m X 3.0 1/s so Speed = 0.75 m/s Wavelenght = 0.25 Frequency = 3.0 Hz Speed = 5 km/s Frequency = 10 Hz 10/5 = 2 so 2X10 = 20 Wavelength = 20 km/s Frequency (u) = 250 Hz Time period (T) = 1/u so 1/250 =0.004s which is the Frequency. Refraction Refraction is the bending of a wave as it enters a new medium at an angle.
Destructive Interference Occurs when two or more waves combine to produce a wave with a smaller displacements. Standing Wave A standing wave is a wave that appears to stay in one place. Reflection occurs when a wave bounces back off a surface that it cannot pass through, Reflection does not change the speed or frequency of a wave, but can be flipped upside down.

When a wave enters a medium at an angle, refraction occurs because one side of the wa moves more slowly than the other side. A wave diffracts more if its wavelength is large compared to the size of an opening or obstacle. A standing wave forms only if half a wavelength or a multiple of half a wavelength fits exactly into the length of a vibrating cord.
