Yes

1. The grilling function is light wave

2. When the microwave oven uses the grilling function, the microwave generator is not started, so tin foil can be used.

3. In the case of microwaves, tinfoil has a reflective effect on microwaves, which will lead to a reduction in the heating efficiency of the microwave oven and poor heating uniformity

Extended information

Microwaves are a kind of electromagnetic waves. Microwave ovens are composed of power supply, magnetron, control circuit and cooking cavity. The power supply provides a high voltage of approximately 4,000 volts to the magnetron. Under the excitation of the power supply, the magnetron continuously generates microwaves, which are then coupled into the cooking cavity through the waveguide system.

There is a rotatable stirrer near the entrance of the cooking cavity. Because the stirrer is a fan-shaped metal, it reflects microwaves in all directions when rotated, so it can spread the microwave energy evenly. Distributed in the cooking cavity to heat food.

The power range of microwave ovens is generally 500 to 1000 watts.
