Question 1

What is an exahertz?

Accepted Answer

10^18 Hz. Beyond current technology. Visible light is ~500 THz (terahertz), far below exahertz.

Question 2

Where would exahertz be used?

Accepted Answer

Theoretical physics, gamma rays approach this range. No practical electronics at exahertz currently.

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.
