Microwaves are used to cook food and transmit information.
What is the wavelength of a microwave that has a frequency of 3.44×10^9 Hz?

Respuesta :

[tex]\\ \rm\Rrightarrow \lambda=\dfrac{c}{\nu}[/tex]

[tex]\\ \rm\Rrightarrow \lambda=\dfrac{3\times 10^8}{3.44\times 10^9}[/tex]

[tex]\\ \rm\Rrightarrow \lambda=0.872\times 10^{-6}[/tex]

[tex]\\ \rm\Rrightarrow \lambda=0.9\mu m[/tex]
