Shorter wavelengths with higher frequencies make up the optical spectrum. The portion of the spectrum that we can see is called the visible spectrum, however, NASA utilizes a number of tools that allow us to communicate and create images utilizing almost every single component of the electromagnetic spectrum in one way or another.
A wave (Figure 2) is a periodic perturbation from an undisturbed or rest state that is transmitted in space. The maximum deviation from this undisturbed state is called the amplitude of the wave, and is a measure of the intensity of the perturbation; the top of the wave is called a crest and the lowest state, a trough.
Draw a picture of a wave and label wavelength and amplitude. What is a wave? A wave is simply energy moving from one place to another. It always needs something to move through. Example: Sound is the wave and the air is the medium. Wave Anatomy. Crest. Wavelength = : : ( ) Trough. In Phase. Amplitude. = : : ( ) Period.

Image source: Haade , CC BY-SA 3.0 , Image is recoloured A stationary wave is formed from the superposition of 2 progressive waves , travelling in opposite directions in the same plane, with the same frequency, wavelength and amplitude.
the waves have the same wavelength, frequency and amplitude, a stationary wave is formed. (Labelled combined wave on the diagram below). The diagram below shows multiple possible standing waves on a displacement-distance graph. The blue points indicate antinodes, while the red points indicate nodes.
