Question
The frequency of the radiation used in all microwave ovens sold in the United States is 2.45 GHz. (1 GHz is a billion cycles per second). What is the wavelength (in meters) of this radiation? How much longer or shorter is this than the wavelength of orange light (625 nm)? The frequency of the radiation used in all microwave ovens sold in the United States is 2.45 GHz. (1 GHz is a billion cycles per second). What is the wavelength (in meters) of this radiation? How much longer or shorter is this than the wavelength of orange light (625 nm)?Explanation / Answer
by using the equation v=f*lamda
lamda=v/f
lamda=3*10^8/(2.45*10^9) = 0.122m
comparing the frequency with orange light
lamda1/lamda2 = 0.122/625*10^-9 = 1.95*10^5 times the wavelength of orange light
