Answer:
Light waves can travel with and without mediums.
Explanation:
Light waves are a type of electromagnetic wave. Some of the characteristics (properties) of light waves include;
I. The wavelengths of light range from 400 nm to 700 nm.
II. Light waves are transverse waves.
III. The speed of light is 3 x 10^8 m/s.
<em>Therefore, from the aforementioned characteristics it can be inferred that light waves can travel with and without mediums.</em>
This ultimately implies that, light wave is an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.
Answer:
Most modern systems of classification are based on evolutionary relationships among organisms – that is, on the organisms' phylogeny. Classification systems based on phylogeny organize species or other groups in ways that reflect our understanding of how they evolved from their common ancestors.
