10-2
10-7
10
10-9
10
-5
Wavelength (cm)
(PLEASE HELP!!)

Answer 1

See explanation

Step-by-step explanation:

When dealing with the Electromagnetic Spectrum, one should remember the acronym ROYGBIV. This will apply to visible spectrum but the non-visible spectra can de logically deduced from the sequence. That is ...

R-Red > O-Orange > Y-Yellow > G-Green > B-Blue > I-Indigo > V-Violet

In relation to the three wave properties; wavelength (λ), frequency (ν) & energy (ΔE) ...

Wavelengths => Long λ Short λ

Frequency => Low ν High ν

Energy => Low ΔE High ΔE

Note that all 'L's' are on the 'Left'

On Left => Long wavelengths, Low frequency & Low energy; the 'opposites' are on 'the other end of the list'.

Therefore for other wavelengths outside the visible spectrum set up as follows, start with visible spectrum in the middle and insert the invisible spectra of interest.

Long λ <= Visible (R.0.Y.G.B.I.V.) => Short λ

λ (cm): 10¹ 10⁻² 10⁻³ (10⁻⁵- 10⁻⁶) 10⁻⁷ 10⁻⁹ (10⁻¹¹ - 10⁻¹³)
