A microwave oven operates with sinusoidal microwaves at a frequency of 2400 mhz. the height of the oven cavity is 25 cm and the base measures 30 cm by 30 cm. assume that microwave energy is generated uniformly on the upper surface of the cavity and propagates directly downward toward the base. the base is lined with a material that completely absorbs microwave energy. the total microwave energy content of the cavity is 0.50 µj. what magnitude force does the microwave beam exert on the base of the oven? (c = 3.00 * 108 m/s, μ0 = 4π * 10-7 t ∙ m/a, ε0 = 8.85 * 10-12 c2/n ∙ m2)

    It takes Δt time to travel the Em wave which is on top of the microwave to bottom of the microwave.

    Δt = h/c

    P = E / Δt = cE/h

    P = 3 * 10⁸ ₓ 0.5 10⁻⁶ / 0.25

    600w.
