2. A sound wave traveling through air has a speed of 346 m/s in a temperature of 25ºC. If the
frequency is 3.9 kHz, what is the wavelength of the sound wave?
3. a). What is the wavelength of a radio wave that has a frequency of 96.5 MHz?
b). What is the period of the radio wave?
4. What is the wavelength of an x-ray 3.1x1012 MHz?
5. Whales in the ocean omit sound waves to one another that can travel enormously long
distances. If two whales are 1500.0 km apart and omit sounds that have a frequency of 19 kHz
and a wavelength of 0.0805 meters. How much time will it take the sounds to travel from one
whale to another whale?
6. 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 attained by this instrument. Assume speed of sound to be 340 m/s.
