In a CRT, electrons leave the filament as the current through the filament heats it upt.  An anode then attracts the free electrons.  According to Newton's second law of motion, the beam of electrons that emerges from the anode aperture will do this.     a.    Decelerate until they reach the fluorescent screen.     b.    Continue accelerating toward the flourescent screen.     c.     Spontaneoulsy decay into photons.     d.    Move at a constant speed toward the fluorescent screen.

What is the essential difference between gamma rays and green light? A. Gamma rays have an electric field, green light do not. B. There is no essential difference in the nature of gamma rays and green light other than he difference in frequency and wavelength. C. Greenlight undergoes refraction, gamma rays I do not D. Gamma rays are a form of radiation, green light is not E. Greenlight is the beam of photons, gamma rays are not photons
