Question 1

What is nanohertz?

Accepted Answer

10^-9 Hz, one billionth of a hertz. Period = 1 billion seconds (~32 years per cycle).

Question 2

Where are nanohertz used?

Accepted Answer

Gravitational wave astronomy, Earth rotation studies, and extremely long-period phenomena.

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.
