Transcript of The parts of Compressional and Transverse waves

Wavelength Wavelength is one point of a wave to another point exactly like it. Amplitude Amplitude has to do with the energy that the wave is transferring. Frequency Frequency is the amount of wavelengths that pass a fixed point per second. Period The period of a wave is how long a wavelength takes to pass a point. Frequency and period are related in a sort of way. What's in a Wave? As you know, there are two types of waves: Transverse & Compressional Now we'll go deeper into what is in each wave... Taylor Wallace Have you heard the words "wavelength", "amplitude", and "frequency"? Do you know what they mean? Well, you'regonna find out! Transverse waves Before we get into wavelength and frequency... you need to know what a crest and trough is. Crest Crest Crest Trough Trough It can be measured by crest to crest,trough to trough, or any other similarpoints. Compressional Waves Don't have crests or troughs, but they do have compressions and rarefactions. In a compressional wave: It's measured from rarefaction to rarefaction or compression to compression It's measured in hertz (Hz). In a transverse wave, you can just count the no. of crests in a wave. Or you can count the no. of troughs. Really, just find out how many wavelengths there are. For compressional waves, do the same, but count rarefactions and compressions, of course. Period= 1/Frequency Frequency= 1/Period Example:

If the Frequency= 5, then the period is 1/5.

If the period is 2, then the freqency is 1/2. Transverse wave: It's measured from crest to resting position, or trough to resting position. The red line shows the amplitude Compressional wave: It's measured by the density of the compressions Wavelength and Frequency are related Frequency and wavelength are indirectly related. They're related because when one is higher, then the other is smaller. So if wavelength is higher, you know that the frequency is smaller. And if the frequency is bigger, then the wavelength is smaller. Wave speed Wave speed (m/s)= frequency (hz) X wavelength (m) This is how to find wave speed So let's say that you have a wave with a frequency of 6 hz and a wavelength of 4 m. What would the wave speed be? The answer's 24 m/s!!!!!

Did you get it right? I hope you understand all the parts of a transverse and compressional wave. Compressions are the parts that are bunched up, and the rarefactions are the parts that are spread apart In a transverse wave: If you're unclear about anything, just look back at the parts you're not sure about, and see how I went through it. You can also look up examples on your own. Have fun!!! :D It's important that you know that the speed that a wave is depends on the medium. That's right, what it goes through affects how fast it is! Sound travels through liquids and solids, and light travels faster through gas. So How Do You Find Wave Speed? Here's the formula to find wave speed: Wave speed= Frequency X Wavelength That's why you can see through oxygen, but not through a wall.
