positive phototaxis.
One use of light spectra has an application in astronomy. When looking at distant objects like galaxies, you can tell if they are moving away from you or closer to you. If the spectral light appears blue (blue-shift) it means that the object is moving toward you, if the spectral light is red (red-shift) it means that the object is moving away from you. Another astronomy application is to look at the light from a star through a spectrum and by doing so you can figure out the chemical composition of the star just by the color of its spectrum.

Fire is a good example of NATURAL light
It depends, if you mean light or sound waves, for example, there are a variety of factors to be measured: The length of a wave from peak to peak is represented with lambda. You can also measure velocity of a wave (how fast and in what direction it is moving). Frequency of light effects the color of the light, and frequency of sound effects its pitch.
No, light is not an example of matter. It is an example of electromagnetic waves. However, it is considered that light is composed of photons (massless particles) and it is applied to it some theories of matter.
moving toward light
Due to the doppler effect, objects moving toward us will be slightly more red than what they actually are, and objects moving away will be slightly more blue. Think of it like a siren coming toward you and moving away from you. If it is moving toward you, it will be slightly higher than what it really sounds like. If it is moving away it will have a slightly lower pitch.
its an response :)
One example is the Doppler effect, where the frequency of waves (such as sound or light) appears higher if the observer is moving toward the source and lower if moving away. Another example is parallax, where the position of nearby objects appears to shift relative to distant objects when viewed from different locations.
If a helicopter is moving toward you at its fastest speed, the color shift in the laser light would be towards the blue end of the spectrum. This is known as a "blueshift" and occurs when the source of light is moving towards the observer, causing the light waves to be compressed and appear more blue.
umm im pretty sure its responce :) hop i helped A plant growing toward light is an example of positive phototropism.
Taxis is the directional movement of the flagella("moving tail"). So... the direction of movement by the prokaryotic cell is described in the taxis. Example: positive phototaxis- positive(toward) photo(light)taxis(movement).
It would mean that the stars are not moving toward you.They could still be moving at appreciable speed across your line of vision,but just not toward you.
Phtosynthesis
The speed of light in the fibre is greater. As a result, light moving toward the outer covering is refracted back towards the core.

If a star is moving toward Earth, it will experience a redshift in its light spectrum due to the Doppler effect. This means that the wavelengths of light will be stretched and appear more red. This effect allows astronomers to measure the speed and direction of a star's movement.
