Question

A microwave oven operates at 3.00 GHz . What is the wavelength of the radiation produced by this appliance? Express the wavelength numerically in nanometers.

Answer 1

Answer:

\lambda=1.00x10^8nm

Explanation:

Hello,

The following formula allows us to relate the speed of light $c$, frequency $f$ and wavelength $\lambda$:

$\lambda=\frac{c}{f}\\\lambda=\frac{3x10^8m/s*\frac{1nm}{1x10^{-9}m} }{3.00GHz*\frac{1x10^9s^{-1}}{1GHz} } \\\lambda=1.00x10^8nm$

Best regards.
