Describe two sources of earth's energy that are not produced

1 answer:

6 0

Here is the answer. Two sources of Earth's energy that are not produced would be Cosmic rays and Tidal Energy. Cosmic rays <span>are high-energy protons and atomic nuclei that come from outside the solar system. Whereas, tidal energy is the energy produced by both the moon (2/3) and the sun (1/3). Hope this answers your question.</span>

Assemble the electromagnetic spectrum by dragging each piece to the correct place on the wavelength scale.

777dan777 [17]

Answer:

long wave with a frequency of nos 10⁶ Hz, to radio waves

* order of 10⁸ Hz TV and FM

* in the 10⁹ to 10¹¹ Hz microwave range

* in the range of 10¹² to 10¹⁴ infrared waves, thermal energy

* in the range of 10¹⁴ visible light captured by humans

* for range 10¹⁵ to 10¹⁸ UV light

* in the range of 10¹⁶ to 10²⁰ X-rays

* for more than 10¹⁹ Hz cosmic rays

Explanation:

The electromagnetic spectrum is formed by transverse waves that are the oscillations of electric and magnetic fields

c = λ f

in general this spectrum is divided into range depending on the uses of the waves

from lower frequency to higher we have

* long wave with a frequency of nos 10⁶ Hz, corresponds to radio waves

* tv wave and modulated frequency, of the order of 10⁸ Hz, television and FM radio

* in the 10⁹ to 10¹¹ Hz microwave range

* in the range of 10¹² to 10¹⁴ infrared waves,

* in the range of 10¹⁴ visible light captured by humans

* for range 10¹⁵ to 10¹⁸ UV light

* in the range of 10¹⁶ to 10²⁰ X-rays

* for more than 10¹⁹ Hz cosmic rays
