How would you describe the connection between the amount of energy a type of electromagnetic wave has and how that wave is used
Mazyrski [523]

Answer:

Uses of various electromagnetic waves depend on their relative energy.

Explanation:

The electromagnetic spectrum is the term used by scientists to describe the entire range of light that exists from radio waves to gamma rays. Electromagnetic waves is a wave of alternating electric and magnetic fields. The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The sun, earth, and other bodies radiate electromagnetic energy of varying wavelengths. Electromagnetic energy passes through space at the speed of light in the form of sinusoidal waves. The spectrum of waves is divided into sections based on wavelength. The shortest waves are gamma rays, which have wavelengths of 10^-6 microns or less. The longest waves are radio waves, which have wavelengths of many kilometers.

The application of various electromagnetic waves in science and technology depends on the energy of the wave. Electromagnetic waves that possess very high amount of energy are used in medical diagnosis, treatment of tumors, searching of baggage and detection of flaws in metal casting. Examples of such electromagnetic waves include gamma rays and xrays.

Some part of the electromagnetic spectrum possess energy enough to excite chemical bonds and produce spectra characteristic of certain functional groups in molecules. The ultraviolet and infrared rays fall into this category.

Some portion of the spectrum possesses very low energy and long wavelength and are mostly used for communication, mild medical diagnosis and resonance imaging/spectroscopy. Radio waves fall into this category.

love history [14]
  • T_1=27°C
  • T_2=40°C
  • V_1=1L
  • V_2=?

Using Charles law

\boxed{\sf \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}}

\\ \sf\longmapsto V_1T_2=V_2T_1

\\ \sf\longmapsto 1(40)=27V_2

\\ \sf\longmapsto V_2=\dfrac{40}{27}

\\ \sf\longmapsto V_2=1.48\ell

6 Which substances have atoms of the same element but different molecular structures?
Bezzdna [24]
Well you want the answer with the same letter in it. A.k.a 2. This means they have the same element in them
O2 (Diatomic oxygen that we breathe) and O3 (Ozone that would be deadly to breathe) have different structures.
So the answer is 2

How does the law conservation of matter apply to machines
IRINA_888 [86]
The Law of Conservation of Matter says that the amount of matter stays the same, even when matter changes form. ... Another way to explain the law of conservation of matter is to say that things cannot be magically created or destroyed. Please mark brainliest?
