Calculate the wavelength of this type of wave.A radio station has a frequency of 90.9 megahertz (9.09 x 107 Hz). What is the wavelength of the radio waves the station emits from its radio tower?An x-ray has a wavelength of 5 nanometers (5.0 x 10-9 m). What is the frequency of x-rays?The ultraviolet rays that cause sunburn are called UV-B rays. They have a wavelength of approximately 300 nanometers (3.0 x 10-7 m). What is the frequency of a UV-B ray?Infrared waves from the sun are what make our skin feel warm on a sunny day. If an infrared wave has a frequency of 3.0 x 1012 Hz, what is its wavelength?The wavelength of water in a ripple tank is 0.085 m. If the wave frequency is 3.5 Hz, what is its speed?The distance between successive crests in a series of water waves is 5.0 m and the crest travels 10 m in 5.5 s. What is the frequency of the wave?It is 24 m from trough to trough in a system of water waves. If 10 waves pass a given point each minute, determine the speed of the waves.The period of a sound wave from a piano is 1.25 x 10-3 s. If the speed of the wave in air is 340 m/s, what is the wavelength?A source with a frequency of 40 H produces water waves that have a wavelength of 1.5 cm. What is the speed of the wave?A wave in a rope travels at a speed of 4.5 m/s. If the wavelength is 2.6 m, what is the period of the wave? ................
