Question

Part A A radio station's channel, such as 100.7 FM or 92.3 FM, is actually its frequency in megahertz (MHz), where 1MHz=106Hz and 1Hz=1s−1. Calculate the broadcast wavelength of the radio station 99.10 FM. Express your answer to four significant figures and include the appropriate units. λ =

Part B Green light has a frequency of about 6.00×1014s−1. What is the energy of green light? Express your answer to three significant figures and include the appropriate units. E =

Part C Hospital X-ray generators emit X-rays with wavelength of about 15.0 nanometers (nm), where 1nm=10−9m. What is the energy of the X-rays? Express your answer to three significant figures and include the appropriate units.
