Your microwave is broken, so the food does not rotate while the microwave is on. You put your food in the microwave, and set the cook time for 3 minutes. After 3 minutes, you take out your food. Parts are hot. Parts are cold. You know that the microwave blasts your food with several different waves together at the same time to heat it up. What wave behavior best describes how these waves interact to create pockets of hot and cold in your food?
Refraction
Reflection
Interference
Polarization
