Frequently Asked Questions
-
What does wavelength in dekametres represent?
-
It represents the spatial period of a wave in units where one dekametre equals ten metres, indicating the physical distance between repeating points such as crests.
-
How is millihertz defined?
-
Millihertz is a frequency unit equal to one thousandth of a hertz, measuring the number of cycles per second at very low frequencies.
-
Why might the conversion not be exact in all cases?
-
Because the conversion assumes wave speed equals the speed of light in vacuum, it may not be precise for waves in other materials or for non-electromagnetic waves.
