Telephone
The telephone was invented in 1876.The light bulb was invented in 1879.
The microwave was invented in 1945.
Henricg Globel invented the first true light built in 1854 in Germany.
The first handheld light meter was invented by Arthur James Dalladay in 1932. He created a light meter that photographers could use to measure the intensity of light for more accurate exposure settings.
The purpose of the light in a microwave oven is to enable the user to observe the progress of the cooking, and to serve as another indication ... in addition to the sound of the fan ... of when the oven is energized. The light is only a convenience, and has no effect on the operation of the appliance.
Microwave ovens use longer light rays than the visible light rays we can see. Microwave radiation has a longer wavelength, which allows it to penetrate and heat food without being visible to the human eye.
Both infrared and microwave light travel at the speed of light in a vacuum, which is about 299,792 kilometers per second. Therefore, they both travel at the same speed.

The light bulb was invented first by Thomas Edison in 1879. The telephone was invented by Alexander Graham Bell in 1876, three years before the light bulb. The microwave oven was invented much later, in 1946 by Percy Spencer.
The first glass light bulb was invented in 1841 by Frederick DeMoleyns. However the first electric lamp was invented in 1806.

No, a microwave does not produce visible light that can be used to light a light bulb. Microwaves generate electromagnetic radiation in the microwave frequency range which is not visible to the human eye.
The microwave energy in a microwave oven is of a much lower frequency than light, but light is electromagnetic energy like the microwave radiation is.
