Answer 1

Reason to why the food is cooked without melting or igniting the plastic container in microwave oven

Explanation:

• The naturally occurring water frequency matches microwave frequency. This is the explanation why it is cooked food containing water.

• The naturally occurring plastic container frequency does not fit microwave frequency. So, no damage to the plastic container.

• Frequency :- Frequency is the number of instances of a recurring event by time unit.  Often called temporary frequency, Which underscores the contrast between spatial frequency and angular frequency.

• The interval is the time span of one cycle in a repeat event, So that time is  frequency is reciprocal .
