7 0

Answer:

Set of electromagnetic radiation.

Explanation:

The electromagnetic spectrum is the energetic distribution of the set of electromagnetic radiation. It consists of <u>electromagnetic waves</u>, which are composed by an electric field and a magnetic field. Every object emits and absorbs these kinds of radiations. This spectrum encompasses from Gamma rays, which are highly energetic electromagnetic waves with high frequency and short wavelength, to Radio waves, which are low energetic electromagnetic waves with low frequency and long wavelength. The visible light, like the sunlight, is only a tiny portion of the electromagnetic spectrum, the rest of the electromagnetic waves are invisible to the human eye, like infrared light, UV light, X-rays, and microwaves, but they can be perceived and be measured with proper filters.

Explain how physical and environmental resources determine how they are used​
den301095 [7]

Answer:

How does the use of physical resources impact the environment?

In short, raw material extraction and processing always impact on the environment, resulting as they do in soil degradation, water shortages, biodiversity loss, damage to ecosystem functions and global warming exacerbation. ... Improper product use provokes noxious emissions that can end up in our water, soil and air.

What are the resources of environment?

Food from plants and animals, wood for cooking, heating, and building, metals, coal , and oil are all environmental resources. Clean land, air, and water are environmental resources, as are the abilities of land, air, and water to absorb society's waste products.

Hope this helps.
