Which everyday morning ritual is part of quantum mechanics?

Ringing of an alarm clock

The correct answer is option 3. Ringing of an alarm clock.

The ringing of an alarm clock is the everyday morning ritual that is part of quantum mechanics.

Quantum mechanics governs the behavior of particles at the atomic and subatomic levels. The workings of electronic devices, including alarm clocks, rely on principles of quantum mechanics, such as the behavior of electrons in semiconductors, the quantum tunneling effect, and quantum superposition. Therefore, the ringing of an alarm clock involves processes and technologies that are grounded in quantum mechanics.
