III Microwaves and radio waves are both members of the electromagnetic spectrum. Which of these statements is/are correct? A I only B III only C I and II ...
1. The musical note A above middle C has a frequency of 440 Hz. If the speed of sound is known to be 350 m/s, what is the wavelength of this note? 2. A certain FM radio station broadcasts electromagnetic waves at a frequency of 9.05×107 Hz. These radio waves travel at a speed of 3.00×108 m/s. What is the wavelength of these radio waves? 3.
ii Use your answer to work out what fraction of a wavelength passes the point D in one second. ..... iii Use the formula speed = time distance to find the speed of the wave. ..... iv Use the formula speed = frequency wavelength to find the frequency of the wave.
Amplitude – Height of wave. Measured from the equilibrium position to the top of a crest or the bottom of a trough (see vertical arrow) Wavelength – length of a single wave cycle (horizontal arrow). Measure distance between 2 identical points on consecutive waves.
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.
