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
