The total energy of a particle, executing simple harmonic motion isAns) In simple harmonic motion when a particle is displaced to a position from its mean position, then its kinetic energy gets converted into potential energy and vice-versa. Therefore, total energy of a particle remains constant or the total energy in simple harmonic motion does not depend on displacement x.
Q. What are de Broglie waves? Matter in motion should be accompanied by waves called de Broglie waves. de Broglie wavelength λ = h / mv
