We're guessing that you have no trouble listening to the radio in your basement,

or watching TV inside in the middle of your house. The so-called "microwaves"

are exactly the same physical phenomenon as radio waves and TV waves.

Their shorter wavelength means that they suffer more loss when they penetrate

material objects, which is why microwave design engineers (ahem ahem) always

try to arrange for clear, unobstructed line of sight for microwave communications.

But that doesn't mean that any solid material instantly stops microwaves dead.

It just means that they can't penetrate quite as far as FM radio and TV can.

The above answer is right , but what i meant is what is the Engineering formulla that claculate the penetration of microwave?

Can microwave waves penetrate through brick walls?

Yes, microwave waves can penetrate through brick walls.


Why does a microwave arc and spark?

A microwave arcs and sparks when metallic objects such as forks or aluminum foil are placed inside, causing a buildup of electrical charge that discharges between the metal and the walls of the microwave. This can be dangerous as it can damage the microwave and pose a fire hazard.


Should the inside walls of a microwave get hot?

Yes, it is normal for the inside walls of a microwave to get hot during operation. This is because the microwave radiation heats up the food and the container, which then transfers heat to the walls of the microwave.


Can ghosts go through walls?

Yes, according to popular belief, ghosts are often thought to be able to pass through walls and other solid objects.


What objects block light?

Objects such as walls, doors, and curtains can block light, while transparent or translucent objects like glass or plastic allow light to pass through. Light is also blocked by opaque objects that are thick enough to prevent light from passing through, such as metal sheets or concrete walls.


What stops microwave radiation from escaping the microwave oven?

The metal walls of the microwave oven reflect and contain the microwave radiation, preventing it from escaping.


Why can't we walk through walls?

We can't walk through walls because the atoms and molecules in our bodies are tightly packed together, creating a barrier that prevents us from passing through solid objects.


Can the flash vibrate through objects?

In some comic book storylines, The Flash can vibrate his molecules at high speed to phase through solid objects. This ability allows him to pass through walls and other barriers.


What objects in the are house are opaque?

Your walls, doors, and furniture are typically opaque objects in the house. They do not allow light to pass through them, which makes them solid and non-transparent.


What i the wasted energy of a microwave?

In a microwave, wasted energy can occur due to heat loss through the walls of the oven, inefficient conversion of electrical energy to microwave radiation, and energy not being absorbed by the food being heated. This can result in lower efficiency and longer cooking times.


Can see through objects?

Seeing through objects like walls or clothing requires advanced technology such as x-ray machines or thermal imaging. It's not possible to naturally see through solid objects with the naked eye due to the way light interacts with matter.


Why is it important that the walls and door of a microwave oven reflect the microwave radiation?

It is important for the walls and door of a microwave oven to reflect microwave radiation to contain and direct the energy inside the cooking chamber. This helps to heat food evenly and efficiently, while preventing leakage of radiation to ensure safety for users.
