Every number shown is a typical value for a countertop microwave: 800 W microwave output (~1200 W mains draw), 2.45 GHz (wavelength ≈ 12.2 cm, standing-wave hot spots ≈ 6.1 cm apart), a ≈30 s duty cycle and a ≈5 rpm turntable. Frozen food is assumed to absorb 10% of the liquid-water rate — the figure's stated ice-rate assumption, not a measurement.
