Amicrowave oven produces energy waves that are longer than visible light shorter than visible light not part of the electromagnetic spectrum

Visible photon has more energy than a microwave photon. A microwave oven pumps out 1,000 watts of energy or more by generating a whole bunch of photons. Your conventional oven actually puts out even more energy (3,000 watts for an electric, 5,000 for gas). Most of that is infrared, which has less energy than visible light but more than a microwave.Thus the answer is shorter than visible light.

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
