The relationship between wave characteristics:
, where v is the propagation speed of the wave, f is the frequency, and λ is the wavelength.
From the boxed equation, we have the wavelength as, λ = v/f
Two microwave frequencies are authorized for use in microwave ovens: 900 and 2560 MHz.
a. Calculate the wavelength of each
b. Which frequency would produce smaller hot spots in foods due to interference effects.
