Calculating the Speed and Frequency of a Wave Directions: Complete calculations. Show all work. speed = wavelength x frequency Remember – the unit of measurement for frequency is expressed in hertz (Hz)

1. An ocean wave has a length of 10. 0 m 1. An ocean wave has a length of 10.0 m. Two waves pass a fixed point every 1.0 s. What is the speed of the wave? Analyze: Write the formula: Substitute and Solve:

2. A wave moving along a rope has a wavelength of 1 2. A wave moving along a rope has a wavelength of 1.2 m and a frequency of 4.5 Hz. How fast is the wave traveling along the rope? Analyze: Write the formula: Substitute and Solve:

3. Earthquakes can produce three types of waves 3. Earthquakes can produce three types of waves. One of these is a transverse wave called an S wave. A typical S wave travels at 5000 m/s. Its wavelength is about 417 m. What is its frequency? Analyze: Write the formula: Substitute and Solve:

4. A tuning fork produces a sound wave with a wavelength of 0 4. A tuning fork produces a sound wave with a wavelength of 0.20 m and a velocity of 25.6 m/s. What is the frequency of the tuning fork? Analyze: Write the formula: Substitute and Solve:

5. A wave travels at a velocity of 4. 0 m/s and has a frequency of 3 5. A wave travels at a velocity of 4.0 m/s and has a frequency of 3.5 Hz. What is the wavelength? Analyze: Write the formula: Substitute and Solve:
