  1. Wave Frequency and Speed Page 43 of INB

  2. EQ How does the medium effect the speed of a wave?

  3. Frequency The frequency of a wave is the number of wavelengths that pass by a point each second. Frequency is related to how rapidly the object or material producing the wave vibrates. Each vibration of the object produces one wavelength.

  4. Wave Speed Different types of waves travel at different speeds. The same type of waves travel at different speeds in different materials. Temperature also affects the speed at which waves travel.

  5. Wave Speed You can calculate the speed of a wave by multiplying its wavelength and its frequency together. Wave speed = Frequency x Wavelength SEE BOARD !!!!!!!!

  6. Practice Problem

  7. Practice Problems Jeremy dove into a pool and made waves. The wave has 1 wavelength every 3 seconds. What is the frequency of the wave? Humans can hear frequencies as low as 21 Hz. If the sound is measured during 3 seconds, how many wavelengths pass? If the frequency of a sound wave is 7.0 Hz, and the sound wave travels through the air at a speed of 350 m/s, what is the wavelength?

  8. 1) A sound wave has a frequency of 627 Hz and a wave length of 3.0 m. What is the speed of the wave? 2) A sound traveling at 252 m/s and has a frequency of 126 Hz. What is the wave length? 3) A sound wave is traveling at 4,800 m/s and has a wavelength of 8 m. What is the frequency of the wave? 4) A sound wave is traveling at 6600 m/s and has a frequency of 600 Hz. What is the wavelength?
