How are waveguides used in Bose shelf stereos?

The Wave systems use a folded waveguide (a series of passages from the speaker driver to the speaker grill). The waveguide is claimed to improve low-frequency sound “from a small enclosure by guiding air through two 26” folded wave guides”.

Why is my radio signal losing so much strength?

If you have an external aerial, a radio signal will always lose some of its strength as it passes along the cable and through the connectors. It is important to minimise the loss by using good quality cable and connectors.

What happens if I stand in front of my microwave?

Even if the shield is faulty, it will not cause any harm. Any (very slight) damage would be caused by heating (and not directly by ‘radiation’), which you most definitely will feel before any real damage. Also, just don’t stand in front of it for hours a day. That always helps. Have something to add to the explanation?

What happens if you Spill Something in your microwave?

Beware, the messy microwave oven. If you spill something in your microwave, clean it up before it seeps into the edge where the door meets the microwave oven, said Drengenberg. Food and liquids that harden and form a crusty mess could create a wedge between the seal of the door allowing microwave energy to escape.

Why does my radio fade away when I turn it on?

Fading: If the radio works, then slowly fades away, then slowly comes good again, it could be an intermittent connection to a valve heater, causing it to warm up then cool down. Check for a dry joint on the valve socket, or a dirty socket.

Can a hole in a microwave cause radiation?

Practically speaking, even a smaller hole would cause some leakage. Although this leakage of radio waves is not “radioactive emission”, many people mistakenly assume that it’s the same as walking past Chernobyl.

Can you repair a radio that has stopped working?

YOU MUST NOT ATTEMPT TO REPAIR THE RADIO YOURSELF UNLESS YOU ARE LEGALLY ALLOWED TO DO SO. The faults can be loosely categorised in two groups. Failures and age. If it was the year 1950 and your near-new radio has stopped, you would look for a failed component.

How does the wave guide work in a microwave oven?

Whenever electricity is passed, it generates microwaves, which are then released inside the oven for heating food. The component called the wave guide projects these waves into the main compartment of the oven, i.e., space where you put your pizza (and other food).
