Physics Girl Microwave Experiment Quiz

What was Dianna's initial assumption about microwaves?

• They can block all types of signals.

• They are completely safe to use.

• They should act as perfect Faraday cages.

• They can cook food faster than ovens.

What did Dianna discover about the microwave's ability to block signals?

• It allowed some cellular signals to pass through.

• It blocked all signals perfectly.

• It only blocked Wi-Fi signals.

• It enhanced the signals.

Where did Dianna find the microwave was leaking signals?

• Through the top vent.

• Through the microwave door.

• Through the back panel.

• Through the power cord.

What did Dianna and Samy use to measure radio frequency signals?

• A spectrum analyzer.

• A voltmeter.

• A thermometer.

• A sound meter.

What was the result when Dianna placed her phone in a real Faraday cage?

• The phone overheated.

• The phone's battery drained quickly.

• The phone stopped transmitting signals.

• The phone continued to receive signals.

What frequency does Wi-Fi commonly use?

• 1.2 gigahertz

• 5.0 gigahertz

• 2.4 gigahertz

• 3.6 gigahertz

What surprising discovery did Dianna make about Wi-Fi and microwaves?

• Wi-Fi signals can penetrate some microwaves.

• Wi-Fi signals are stronger than microwave signals.

• Wi-Fi signals are unaffected by any barriers.

• Wi-Fi signals are completely blocked by microwaves.

What is the primary concern with microwave leakage?

• It can heat up tissues with concentrated exposure.

• It can cause food to spoil.

• It can interfere with television signals.

• It can cause electrical fires.

What factor did Dianna mention could affect the experiment's results?

• The color of the microwave.

• The age and location of the microwave.

• The type of food being cooked.

• The brand of the microwave.

What property of Faraday cages might explain the leakage observed?

• They are made of plastic.

• They require electricity to function.

• They have holes smaller than the wavelength they block.

• They are only effective against sound waves.
