Final answer:

An electromagnetic wave measured at 30 nanometers from crest to crest would be categorized as an ultraviolet (UV) wave. This places it in a specific portion of the electromagnetic spectrum, and exemplifies the wave-like characteristics of electromagnetic radiation, which are transverse waves.

Step-by-step explanation:

An electromagnetic wave with a distance of 30 nanometers from crest to crest is classified according to its wavelength, which in this case falls into the range of ultraviolet light. The wavelength (λ) defines the type of electromagnetic wave, which can range from radio waves at the longest wavelengths to gamma rays at the shortest wavelengths.

Ultraviolet waves are a type of electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays, therefore, a 30 nm wave is considered ultraviolet (UV) radiation. Electromagnetic waves are characterized as transverse waves, where the electric and magnetic fields oscillate perpendicularly to the direction of propagation.

To illustrate this concept, consider a wave function such as y (x, t) = 0.3 m sin (2.00 m⁻¹x - • 628.00 s⁻¹t), which describes the wave's behavior at any given point and time. The wavelength is an important property of waves, be they in water, air (sound), or electromagnetic (like light), and it helps categorize the type of electromagnetic radiation.

Well, I recognize them by frequency, so let's see . . .

Frequency = (speed) / (wavelength)

Speed = around 3 x 10⁸ m/s in vacuum

Frequency = (3 x 10⁸ m/s) / (30 x 10⁻⁹ m) = 1 x 10¹⁶ Hz.

That's a frequency I don't recognize,
so I gotta go lookit up.

30 nanometers is a hard hard X-ray.
At 10¹⁹ Hz . . . 1,000 times higher freq/shorter wavelength . . .
it would be considered a gamma ray. But this one is just a
hard, hard X-ray.
