Wave Parts & Properties

Longitudinal Wave Fill in the parts for the following longitudinal wave using the following terms (be sure to spell them correctly): compression, rarefaction, wavelength wavelength compression rarefaction Transverse Wave Fill in the parts for the transverse wave using the following words (be sure to spell them correctly): crest, trough, resting point, amplitude, wavelength crest wavelength amplitude resting point trough What relationship exists between wavelength and frequency? As wavelength increases, frequency increases As wavelength increases, frequency decreases Select the correct word that fits in each blank. Waves are a transfer energy that travels through a medium. A transverse wave causes particles in matter to move back and forth at right angles (perpendicular) to the direction in which the wave travels. High points in a transverse wave are called crests. Low points are called troughs. A longitudinal wave causes particles in matter to move back and forth along the same direction in which the wave travels. The places in a compressional wave in which the coils are squeezed together are called compressions. The places in the wave in which the coils are spread apart are called rarefaction. The wavelength of a transverse wave is the distance between two adjacent crests or two adjacent troughs. The wavelength of a compressional wave is the distance between two adjacent compressions or rarefactions. The frequency of a wave is the number of wavelengths that pass by a point each second. Frequency is measured in units of Hertz. As the wavelength of a wave increases, the frequency of the wave decreases. To make a wavelength shorter, one should shake the rope at a higher frequency. The period of a wave is the time it takes a wave to complete one cycle . Sort each image into the correct category based on wavelength. Longest Wavelength Shorter Wavelength Shortest Wavelength Sort each image into the correct category based on amplitude. Highest Amplitude Lower Amplitude Lowest Amplitude Sort each image into the correct category based on frequency. Highest Frequency Lower Frequency Lowest Frequency Which of these longitudinal waves contains 3 complete wavelengths? Which of these transverse waves contains 3 complete wavelengths? The wavelength of a string is 10 m and the frequency is 5 Hz. If we double the frequency, what happens to the wave's wavelength? increases decreases stays the same The wavelength of a string is 10 m and the frequency is 5 Hz. If we double the frequency, what happens to the wave's velocity? increases decreases stays the same Put the following radio frequencies in order from lowest to highest. Lowest Frequency 93.9 MHz Higher Frequency 97.9 MHz Even Higher Frequency 101.1 MHz Highest Frequency 103.5 MHz Put the following radio frequencies in order from shortest to longest wavelength. Shortest Wavelength 103.5 MHz Longer Wavelength 101.1 MHz Even Longer Wavelength 97.9 MHz Longest Wavelength 93.9 MHz If the speed of a sound wave increases, what other property of the wave must also increase when all other properties are held constant? frequency amplitude wavelength The frequency of a transverse wave increases. What happens to the amount of energy that is transferred through the wave? inreases decreases stays the same Using the image, how many crests have been created using this rope? 1 2 3 Using the image, what is the measurement from the person's hand up to the first crest? wavelength amplitude frequency If the speed of a wave decreases, what will increase? wavelength amplitude frequency A teacher attaches a slinky to a fixed wall. The teacher alters the movement of the slinky in two demonstrations like the image below shows:What property of the wave is the teacher primarily changing? wavelength amplitude frequency
