- B2 3 4 1
- C4 3 2 1
- D1 4 3 2
Correct answer
C. 4 3 2 1
Step-by-step solution
(A) Waves of range 1 ~nm to 400 ~nm are produced when inner shell electrons in atoms moving from one energy level to a lower level. (B) The waves of range of wavelength greater the 0.1 ~nm is produced when rapid acceleration and deceleration of electrons in aerials takes place. (C) The waves of wavelength range 1 ~nm to 700 ~nm are produced by the vibration of atom and molecules in a substance. (D) The waves of range of wavelength of less than 10⁻³ ~nm are produced by the radioactive decay of the nucleus. The corre
