1. A wave traveling in the positive x direction with a frequency of 25H is shown in the picture to the right. Find the following values for this wave: a) amplitude b) height c) wavelength d) period e) -14em speed 6em 2. UV radiation from the sun travels at the speed of light, 3x10#m/s with a frequency of 5x10"Hz. What is the wavelength of this UV radiation? 3. You dip your finger into a pan of water 4 times every 2 seconds, producing waves with crests that are separated by 0.12m. Determine the following about these waves: a) frequency b) period c) speed 4. A person (person 1) shouts at a frequency of 120Hz and creates a sound wave that moves at 343m/s. Another person (person 2) shouts at a frequency of 413.25Hz and creates a sound wave that is 0.83m long. a) What is the wavelength of the first person's sound wave? b) What is the speed of the second person's sound wave? 5. Using the two graphs below that represent a wave. One is a graph of amplitude vs. position, and one is amplitude vs. time. Calculate the following: a) amplitude b) 2m wavelength c) period d) frequency e) velocity 0.65 .2m 6. While standing on a cliff, you whistle with a frequency of 600Hz and a wavelength of 56.7cm. You hear the echo of the whistle from the base of the cliff 1.8s after you whistle. How high is the cliff
