Question
1. Radio wave radiation falls in the wavelength region of 10.0 to 1000 meters.
What is the energy of radio wave radiation that has a wavelength of 938 m?
Energy = _____ kJ/photon
2. Gamma ray radiation falls in the wavelength region of 1.00×10-16 to 1.00×10-11 meters.
What is the wavelength of gamma ray radiation that has an energy of 1.99×10-12 kJ?
Wavelength = _____ m
3.
Which region of the electromagnetic spectrum are each of these wavelengths near?
Compare the de Broglie wavelength of an electron moving at 1.30×107 miles per hour (5.81×106 m/s) to that of a bullet moving at 700 miles per hour (313 m/s) and a golf ball with a speed of 70.0 miles per hour (31.3 m/s).Explanation / Answer
Radiowave
WL = 938 m
E = h*c/WL
E = (6.626*10^-34)*(3*10^8)/(938) = 2.1191*10^-18 J/photon
E = 2.1191*10^-15 kJ/photon
