Which outcome occurs when a microwave oven standing wave exhibits multiple antinodes?

💡 Explanation

Uneven heating occurs because standing waves create hot and cold spots, resulting from constructive and destructive interference; this is "spatial variation". A uniform EM field cannot be established, therefore creating cold spots rather than efficient or complete general heating under normal operating conditions.
