Question

Properties of Waves

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 106.3 FM.

Express your answer to four significant figures and include the appropriate units.

Part B

Green light has a frequency of about 6.00×1014s−1. What is the energy of a photon of green light?

Express your answer to three significant figures and include the appropriate units.

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 a photon of the X-rays?

Express your answer to three significant figures and include the appropriate units.
