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: air mass
Explanation: An air mass is a large body of air with generally uniform temperature and humidity. The area over which an air mass originates is what provides its characteristics. As such, air masses are associated with high pressure systems.
<u>Answer:</u>
Ecosystem is the level of organization which includes a community, population, and an individual.
<u>Explanation:</u>
- An ecosystem is the dynamic system of biotic and abiotic components that helps to maintain the circle of life.
- In an ecosystem there are different species and population of those species that exist together within a physical environment that is composed up of soil, water, minerals as well as weather conditions and climates.
- In ecosystem, there is the food chain as well as food web. The change in any component of the biotic or abiotic component would bring about change in every other component. Each component is interrelated with one another in an ecosystem.
