The figure shows a standing electromagnetic wave in a 690 W microwave oven. The oven has a length of 1 = 0.21 m and a square cross-section of side w = 0.80 m. The electric field is shown in red and the magnetic field in blue at one instant. The standing wave has 4 nodes in the interior of the microwave and both E and B go to zero at the sides. The electric field reaches its peak magnitude on the cross-sectional area, A. Take the speed of light in the oven to bec= 3.00 - 10°m/s A Part A - What is the wavelength of the standing wave in the microwave?
