Name:__ __Answer Key Date:__ Waves Worksheet #2 Frequency Wave 1: 1. How many wavelengths long is Wave 1? 2 wavelengths 2. How many wavelengths long is Wave 2? 2.5 wavelengths Wave 2: 3. How many wavelengths long is Wave 3? 1.5 wavelengths 4. Which wave has the highest frequency? Wave 2 Wave 3: 5. Which wave has the lowest frequency? Wave 3 6. What is the definition of frequency? The number of waves in a given time. 7. How can you tell by looking at it if a wave has high or low frequency? How close or spread out the waves are Frequency Connection There are three members of a family. The dad has a deep, low voice. The mom has a medium-high voice, and the baby has the highest voice. 8. Which wave belongs to the dad’s voice?_____Wave 3_______________ 9. Which wave belongs to the mom’s voice?____Wave 1_______________ 10.Which wave belongs to the baby’s voice?____Wave 2______________ Amplitude Wave 4: 1. Which wave has the highest amplitude? Wave 5: Wave 5 2. Which wave has the lowest amplitude? Wave 4 3. Use a ruler and measure the amplitude of Wave 5: ~ 0.5 inches 4. What is the definition of amplitude? The distance from the center/resting point to the crest/trough Wave 6: 5. How can you tell by looking at it if a wave has high or low amplitude? By how tall the wave is (or varied responses) Amplitude Connection Juan is playing the piano. The music starts of at meso-forte (medium high volume). It then crescendos into forte (loud) and Juan plays dramatically. The music ends at piano (quietly) with a sweet melody. 6. Which wave represents the music at the beginning?_______Wave 6_____________ 7. Which wave represents the music in the middle?__________Wave 5____________ 8. Which wave represents the music at the end?____________Wave 4_____________ Final Waves Goodbye Compare waves A-D by both amplitude and frequency to the Standard Wave. (Higher/Lower/Same) Standard Wave A B __Higher____Amplitude; ___Same____Frequency ___Lower___Amplitude; ___Higher____Frequency C D ___Same___Amplitude; ___Lower____Frequency ___Higher____Amplitude; ___Higher___Frequency
