Calculate the speed of the wave. EquationRearranged EquationWorkFinal Answer  The speed of sound in air is about 340 m/s. What is the wavelength of sound waves produced by a guitar string vibrating at 490 Hz? EquationRearranged EquationWorkFinal Answer  The speed of light is 300,000,000 m/s. What is the frequency of microwaves with a wavelength of 0.01 meter? EquationRearranged EquationWorkFinal Answer  What is the period of the microwaves in the above question? EquationRearranged EquationWorkFinal Answer The string on a piano that produces an A sharp vibrates with a frequency of 235 Hz. If the sound waves produced by this string have a wavelength in air of 1.49 meters, what is the speed of sound in air? EquationRearranged EquationWorkFinal Answer  The average wavelength in a series of ocean waves is 15.0 meters. A wave crest arrives at the shore on an average of every 10.0 seconds, so the frequency is 0.100 Hz. What is the average speed of the waves? EquationRearranged EquationWorkFinal Answer  An FM radio station broadcasts electromagnetic waves at a frequency of 94.5 MHz (equal to 94,500,000 Hz). These radio waves have a wavelength of 3.17 meters. What is the speed of the waves? EquationRearranged EquationWorkFinal Answer  Green light has a wavelength of 0.00000052 meters. The speed of light is 300,000,000 m/s. Calculate the frequency of green light waves with this wavelength.
