Waves: Solved Exercises Part 2
Questions about wave motion involving the notions of wavelength, speed, and frequency.
1) A radio station, in the FM (Frequency Modulation) band, transmits using waves with a wavelength of 3.0 m. Given that the speed of electromagnetic waves in air is 3.0 x 10⁸ m/s, what is the frequency of this radio station? Give the answer in MHz.
2) The figure represents a section of a wave propagating at a speed of 300 m/s.
For this wave, determine:
a) the amplitude;
b) the wavelength;
c) the frequency;
d) the period.
3) The figure represents the propagation of a wave along a string with a frequency of 20 Hz. What is the propagation speed of this wave?
