Amicrowave oven operates at 2.00 ghz . what is the wavelength of the radiation produced by this appliance? express the wavelength numerically in nanometers.

Since frequency and wavelength have inverse relationship. It can be expressed by the equation: ν.λ = c Where, v = frequency of the electromagnetic wave. λ = it's wavelength c = the speed of light in a vacuum. v = 2.00 Ghz x 10^9 Hz / 1 Ghz = 2.00 x 10^9 Hz that means that in one second it covers 2.00 x 10^9 cycles. λ = 3.10^8 m/s / 2.00 x 10^9 /s = 1.25E-10 nanometers
