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.
What is a simple definition of microwave radiation?
Microwave radiation is a type of electromagnetic radiation with wavelengths ranging from about 1 millimeter to 1 meter. It is commonly used in technology such as microwave ovens, communication networks, and radar systems.
How was microwave radition discovered?
Microwave radiation was discovered by physicist Percy Spencer in 1945. He noticed that a candy bar in his pocket melted while working with a magnetron, a vacuum tube that generates microwaves. Spencer then conducted further experiments using popcorn and an egg, leading to the development of the first microwave oven.
Who were the two scientists that discovered CBR and how did they discover it?
The Cosmic Microwave Background Radiation (CBR) was discovered by Arno Penzias and Robert Wilson in 1965. They were working on a radio telescope and found an unexpected source of noise that turned out to be radiation left over from the early universe, providing evidence for the Big Bang theory.
Does a microwave transfer heat by radiation?
Yes, a microwave transfers heat through radiation. Microwave ovens use electromagnetic radiation in the microwave frequency range to heat food by causing water molecules in the food to vibrate and generate heat.
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.
What did Penzias and Wilson discover?
Penzias and Wilson discovered the cosmic microwave background radiation in 1965, providing strong evidence for the Big Bang theory of the origin of the universe. This discovery earned them the Nobel Prize in Physics in 1978.

Microwave radiation is a type of electromagnetic radiation with wavelengths ranging from about 1 millimeter to 1 meter. It is commonly used in technology such as microwave ovens, communication networks, and radar systems.
How was Cosmic Microwave background radiation first discovered?
It as predicted from theory and discovered by accident by two telephone engineers that, when they saw it, thought it was some sort of interference noise in their instrument, (possibly caused by pigeons). When they were unable to eliminate the noise, they spoke about it to an academic friend who realised that what they were detecting may be the predicted microwave background radiation.

Do microwave ovens use electromagnetic radiation?
Yes, microwave ovens use electromagnetic radiation.

The heat left over from the beginning of the universe is?
cosmic microwave background radiation.
Does a microwave transfer heat by radiation?
Yes, a microwave transfers heat through radiation. Microwave ovens use electromagnetic radiation in the microwave frequency range to heat food by causing water molecules in the food to vibrate and generate heat.
Is there UV in microwave ovens?
No, microwave ovens do not emit ultraviolet (UV) radiation. They use microwave radiation to heat and cook food by causing water molecules in the food to vibrate, generating heat. UV radiation is not involved in the operation of microwave ovens.
What kind of compound is microwave?
Microwave is applying microwave radiation to chemical reaction.
Is microwave radiation dangerous?
Microwave radiation can be dangerous at high levels if proper safety precautions are not followed. Exposure to high levels of microwave radiation can cause tissue heating and damage, leading to various health effects. It's important to follow guidelines and safety instructions when using microwave ovens or working in environments with exposure to microwave radiation.
