What makes the light change colors?

Click here for the answer When the photons in the tube have a greater or lesser charge

Why does the light move when you put a magnet to the tube?

Click here for the answer The energy levels reached by the electrons depend more on the electronic structure of the atoms themselves, and therefore the photons emitted tend to be clustered around specific wavethenghs.

 

 PPhilo T. Farnsworth

Date discoverd 1928

 

Philo T. Farnswoth was born on August 9, 1906, in Beaver, Utah, and died on March 11, 1971. Philo's electronic inventions took all of the moving parts out of televisions and made possible today's TV industry, the TV shots from the moon, and satellite pictures. He was educated in Utah and Idaho public school systems and went to Brigham Young University. He left after two years due to the death of his father, and soon afterword enrolled in Crocker Research Laboratories in San Fransico. At the age of twenty he invented the first all-electric television image. He also invented the first cold cathode ray tubes and the first simple electronic microscope. When he died at age 64 he held more than 300 U.S. and foreign patents.
