Wavelength has inverse relationship with its energy. The shorter the wavelength, the higher the energy.

Complete question was:
Which of the following transitions (in a hydrogen atom) represent emission of the longest wavelength photon?n = 1 to n = 2 <span>n = 3 to n = 1 </span>
<span>n = 3 to n = 4 </span>
<span>n = 4 to n = 2 </span>
<span>n = 5 to n = 4
</span>
The longest wavelength photon is n = 5 to n = 4. As I stated above,the wavelength and energy has inverse relationship. The longest wavelength has the lowest energy.

The correct answer is:

The longest wavelength photon is n = 5 to n = 4.

The explanation:

According to he relation between the wavelength and energy, there have inverse relationship. The longest wavelength has the lowest energy.

and when:

-Transitions to n=1 are in the UV part of the spectrum and have the shortest wavelengths.

-and Transitions to n=2 are in the visible part of the spectrum and have wavelengths between 700nm and around 400 nm

-and Transitions to n=3 or greater are in the infra-red part of the spectrum and have the longest wavelengths.

- So the longest wavelength would correspond to the lowest energy and that would correspond to the difference in energy between n=5 and n=4

On the basis of significant figures, the accuracy of measurement made using an analytical balance is more reliable.

<h3>What is an analytical balance?</h3>

An analytical balance is a special type of weighing balance that has a reputation for obtaining the mass of very small objects even as low as milligrams. It consists of a transparent glass casing and a scale.

On the basis of significant figures, the use of an analytical balance to determine the weight will improve the accuracy of the determination since it determines the mass to more significant figures.

Which one of the following descriptions relating to nuclear reactions is correct?

monitta

Answer: option D - The total number of nucleons changes.

Explanation:

Nuclear Reaction is best described as a process such as the fission of an atomic nucleus, or the fusion of one or more atomic nuclei and / or subatomic particles in which the NUMBER of PROTONS and / or NEUTRONS in a nucleus CHANGES; the reaction products may contain a different element or a different isotope of the same element.

Note that the NUCLEONS refers to ONE of the subatomic particles of the atomic nucleus, i.e. a PROTON or a NEUTRON.

So, in a Nuclear reaction, the total number of nucleons changes.

Describe the three main types of plate boundary interactions:

bulgar [2K]

Answer:

In the explanation

Explanation:

Divergent: When two plates are diverging from each other, meaning that the two plates are moving away from each other. Events that may occur include ridges or rifts.

Convergent: When two plates are moving towards each other.

If a continental plate and an oceanic plate are converging, the oceanic plate would slide underneath the continental plate since it is thinner. This would result in subduction, which means that part of the oceanic plate would hang underneath the continental plate, where magma can melt the hanging part.

If two continental plates are converging, the crash would result in mountains or volcanic activity. Magma could rise and rush from the crack. There would be a bump in these tectonic plates.

Transform: When two plates are sliding past each other. Earthquakes can occur when the plates are sliding. When an oceanic plate is involved, the movement of the plates could cause a tsunami as well. The water above the transform fault could rise, and grow bigger and bigger. The 2011 Japan Tsunami is a good example of this.

Hope this helps!
