gamma radiation is both a type of nuclear radiation and electromagnetic radiation.
Radiation has both electric and magnetic fields and travels in waves. It comes from natural and man-made sources. The intensity of electromagnetic radiation varies from low energy to high energy. There are radio waves, microwaves, infrared rays, visible rays, ultraviolet rays, X-rays, and gamma rays.
Electromagnetic radiation consists of an electric field (E) of varying strength perpendicular to the direction of propagation of the radiation and a magnetic field (M) perpendicular to the electric field. Both fields move at the speed of light (c).
Electromagnetic radiation occurs when atoms absorb energy. The absorbed energy causes one or more electrons to change positions within the atom. Electromagnetic waves are generated when electrons return to their original positions.

B would the correct answer
Answer:
Explanation:
What is the difference between elaborative rehearsal and maintenance rehearsal in terms of (a) the procedures associated with each type of rehearsal and (b) their effectiveness for creating long-term memories
Elaborative rehearsal is connecting what you're trying to know to something you already know; is much effective for creating long-term memories
; involves thinking the meaning, and making a connection to prior knowledge
Maintenance rehearsal simply means holding something in your memory by repeating it over and over rather than connecting it to something meaningful; involves large repetition without connection to prior knowledge;not very effective for creating long-term memories and involves shallow processing with little attention to meaning
