Question 1

How do frequency and wavelength relate?

Accepted Answer

λ = c/f. Wavelength = speed of light / frequency. Higher frequency = shorter wavelength.

Question 2

What is the speed of light in this formula?

Accepted Answer

c = 299,792,458 m/s in vacuum. Radio waves, light, and all EM radiation use this relationship.

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.
