Unit 10: Introduction to Waves 1. What is the period of a wave with a frequency of 250 Hz?

2. What is the wavelength of a sound wave whose speed is 330m/s and whose frequency is 990 Hz?

3. The frequency of a water wave is 6.0 Hz. If its wavelength is 2 m, what is the speed?

4. If a wave that is traveling at 3x10 6 m/s has a period of 0.04s, what is it's wavelength?

5. A light wave traveling through a vacuum has a frequency of 6.67 x 10 14 Hz has what wavelength? (Hint: The speed of light in a vacuum is always 3x10 8 m/s!)
