On its highest power setting, a certain microwave oven projects 1.00 kW of microwaves onto a 30.0
Question:
On its highest power setting, a certain microwave oven projects 1.00 kW of microwaves onto a 30.0 by 40.0 cm area.
(a) What is the intensity in W/m2?
(b) Calculate the peak electric field strength E0 in these waves.
(c) What is the peak magnetic field strength B0?
Strategy
In part (a), we can find intensity from its definition as power per unit area. Once the intensity is known, we can use the equations below to find the field strengths asked for in parts (b) and (c).
