Answer 1

The Correct Option is C

Step 1: Microwaves are produced by special vacuum tubes like the Magnetron.
Step 2: Infrared waves are produced by the vibration of atoms/molecules (thermal motion).
Step 3: Gamma Rays originate from the radioactive decay of atomic nuclei.
Step 4: X-rays are produced by transitions of inner shell electrons or deceleration of fast electrons. [Image of electromagnetic spectrum and sources]
