What type of wave is this: Label the following parts: crest, trough, amplitude, wavelength, equilibrium position 1. What is the period of a radio wave that has a frequency of 88.0 x10: Hz? 2. What is the frequency of a wave that has a period of 5 seconds? 3. What is the frequency if 15 waves passed in 1.5 seconds? 4. The speed of all electromagnetic waves in empty space is 3.00 x 10 m/s. Calculate the wavelength of electromagnetic waves emitted at the following frequencies: a. Radio waves at 88.0 x 10% Hz b. Visible light at 6.0 x 1014 Hz c. X rays at 3.0 x 1018 Hz 5. A piano emits frequencies that range from a low of about 28 Hz to a high of about 4200 Hz. Find the range of wavelengths in air attained by this instrument when the speed of sound in air is 340 m/'s. 6. The red light emitted by a laser has a wavelength of 633 x 10-9 m in air and travels at 3.00 x 10' m/s. Find the frequency of the laser light. 7. A tuning fork produces a sound with a frequency of 256 Hz and a wavelength in air of 1.35 m. a. What does this give for the speed of sound in air? b. What would be the wavelength of this same sound in water which sound travels at 1500 m/'s
