Waves WorksheetFree Response Section14) A wave having a frequency of 250 Hz has a wavelength of 43 cm.a. What is the period of the wave?b. What is the speed of the wave?15) All light waves travel through space at the same speed, 3.00 x 10 8 m/s. Use the average earthto sun distance of 1.50 x 10 11 m to calculate the time it takes for light to travel to the earth.Express you answer in minutes to a precision of two decimal places.16) Middle C on a piano produces a sound wave with a frequency of 532 Hz. At 20 o C soundtravels at 343 m/s in air. Calculate the wavelength of this sound wave.
