07. How do scientists use spectroscopy (the study of light frequencies released

Vera_Pavlovna [14]

Every element is able to be recognized individually in many different ways. A very easy and common way is using light absorption also known as spectroscopy. Every atom has electrons, and these electrons like to stay in their lowest-energy configuration. However, when photons collide with an electron it can increase it to a higher energy level.. This is absorption, and each element’s electrons absorb light at specific wavelengths related to the difference between energy levels in that atom. But the electrons want to return to their original levels, so they don’t hold onto the energy for long. When they emit the energy, they release photons with exactly the same wavelengths of light that were absorbed in the first place. An electron can release this light in any direction, so most of the light is emitted in directions away from our line of sight. Therefore, a dark line appears in the spectrum at that particular wavelength.

Because the wavelengths at which absorption lines occur are unique for each element, astronomers can measure the position of the lines to determine which elements are present in a target. The amount of light that is absorbed can also provide information about how much of each element is present.

describe the charge, mass and the location of each subatomic particle and the role each plays in determining the properties of a

Harrizon [31]

Explanation :

An atom is a smallest particle of matter. An atom consists of protons, neutrons and electrons. These are three subatomic particles.

Protons are positively charged species while neutrons are negatively charged species. Electrons revolves around an atom.

Charge :

The charge of an electron is negative or $-1.6\times 10^{-19} \ C$

The charge of proton is +e or $1.6\times 10^{-19} \ C$

Neutron has no charge.

Mass :

Atomic mass of electron is $9.1\times10^{-31}\ Kg$

Atomic mass of proton is $1.67\times10^{-27}\ Kg$

Atomic mass of neutron is $1.67\times10^{-27}\ Kg$

Both protons and neutrons are located inside the nucleus at the center.

Charge, atomic mass and location determines the properties of an atom. Atomic mass tells about the number of protons and neutrons inside an atom. Electric charge tells us the number of electrons gain or lost.

Check all the true statements about sound and light waves.

bixtya [17]

Answer:

See explanation.

Explanation:

Let us go through each of statements one by one.

Light waves may travel either through a transparent medium or through empty space.

Yes, light travels through empty space as well as through transparent media, however, in the latter its speed is slowed down.

Sound waves travel through all substances.

Sound waves are vibrations in a medium. All substances can vibrate; therefore, sound travels through all substances.

Light waves are absorbed and reflected by opaque materials so that no light travels through them.

This is true. The reason light does not pass through an opaque substance is because it is absorbed or reflected way from us.

Light waves cannot travel through empty space.

No, <em>electromagnetic radiation can travel through empty space</em> because it is not a disturbance in a medium.

Sound waves do not require a medium for traveling,

Nope. Sound waves are disturbances in a medium—they cannot exist independent; therefore, they require a medium for travelling.

Sound waves can only travel through transparent objects

No. Sound waves travel through all substances that can vibrate.

Sound waves require a medium for traveling,

As sound waves are vibrations in a medium, they need medium in which they can exist and travel.
