- LABELING WAVES
A student makes the following statements about microwaves and radio waves. I In air, microwaves travel faster than radio waves. II In air, microwaves have a longer wavelength than radio waves.
Problems for you to try: Complete the following practice problems. You MUST show ALL the work outlined in the steps in the example problems. A wave with a frequency of 14 Hz has a wavelength of 3 meters.
Physics P Worksheet 9-4: Waves 8. Consider a wave generator that produces 10 oscillations per second. The speed of the waves is 300.0 cm/s. a. What is the wavelength of the waves? b. What happens to the wavelength if the frequency of pulses is increased? 9. A wave on a lake passes by two docks that are 40.0 m apart. a.
Part 1. In the diagram below, identify the parts of a wave by using the provided definitions. Part 2. On separate sheets of graph paper, draw four different waves with the following measurements. Label the parts and include the measurements.
Wavelength – length of a single wave cycle (horizontal arrow). Measure distance between 2 identical points on consecutive waves. Frequency-# of waves that pass a point in a given amount of time Units=Hz=waves/second Speed = wavelength x frequency.
