# Problem: Two microwave frequencies are authorized for use in microwave ovens: 900 and 2560 MHz. a. Calculate the wavelength of eachb. Which frequency would produce smaller hot spots in foods due to interference effects.

###### FREE Expert Solution

The relationship between wave characteristics:

$\overline{){\mathbf{v}}{\mathbf{=}}{\mathbf{f}}{\mathbf{\lambda }}}$, where v is the propagation speed of the wave, f is the frequency, and λ is the wavelength.

a.

From the boxed equation, we have the wavelength as, λ = v/f
