The video explores whether microwaves act as Faraday cages by testing if they block cellular signals. It reveals that some microwaves leak signals, allowing cellular and Wi-Fi frequencies to pass through. The experiment uses a spectrum analyzer to measure frequencies and demonstrates the effectiveness of a real Faraday cage. It concludes that microwave leakage varies and is influenced by factors like microwave age and location. The video highlights the frequency overlap between Wi-Fi and microwaves, explaining that while microwaves are regulated, small leakage is permissible and not harmful.

What was the initial expectation about the microwave's ability to block signals?

• It would amplify signals.

• It would convert signals.

• It would act as a Faraday cage.

• It would distort signals.

Where was the leak found in the microwave during the experiment?

• At the bottom of the microwave.

• At the back of the microwave.

• On the top of the microwave.

• Around the microwave door.
