Question

Constants I Periodic Table Electromagnetic radiation behaves both as particles (called photons) and as waves. Wavelength (A) and frequency (u) are related according to the equation where c s the speed of light 3.00 × 108 m/s). The energy (En les co tared in one quantum of electromagnetic radiation is desorbed by the equation where h is Planck's constant (6.626 x 10J s)Note that frequency has units of inverse seconds (s-1), which are more commonly expressed as hertz (Hz). Part A A microwave oven operates at 2.60 GHz. What is the wavelength of the radiation produced by this appliance? Express the wavelength numerically in nanometers. View Available Hint(s) nrm Submit

Explanation / Answer

C = Wavelength X Frequency
Speed of light, C = 3 X 108 m/s
Frequency = 2.6 GHz = 2.6 X 109 Hz = 2.6 X 109 /sec

Wavelength = C/frequency
= (3 X 108)/(2.6 X 109)
= 0.1153 m
= 1.153 X 108 nm
