An oscillating electric dipole at the origin is aligned with the s-axis, has dipole maguitude po, and oscillates at angular frequency w. it emits electro- magnetic radiation with steady power. why both the electric and magnetic fields in the radiation zone must lain decrease with distance from the origin as 1/r. explain contribution to radiation why there is no from the fields proportional to 1/r" with a 1.

heats surface water up

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
