Question 1

What is picohertz?

Accepted Answer

10^-12 Hz. Period = 1 trillion seconds (~32,000 years). Theoretical, not practically measured.

Question 2

Is picohertz useful?

Accepted Answer

Primarily theoretical. Geological and astronomical timescales. No electronic oscillators this slow.

Question 3

What's the relationship between frequency and wavelength?

Accepted Answer

They're inversely related: wavelength × frequency = wave speed. For sound in air: wavelength (m) ≈ 343 / frequency (Hz).

Question 4

Why use Hz vs RPM?

Accepted Answer

Hz (cycles per second) is universal for waves and oscillations. RPM (revolutions per minute) is more intuitive for rotating machinery and engines.
