evablogger [386]

Answer:

The diagram shows oxygen, O₂, which consists of two atoms of oxygen in the stratosphere, which are the two beings holding hands, forming a couple being broken up by the intense ultraviolet radiation of the Sun, such that the couple closest to the Sun are the ones that were broken into two O, atoms.

After being broken, the two beings (oxygen atoms), become free to move as they please, making them able to move faster than when they were still a couple. However, due to the likeness for their fellow beings, each of the single O beings rushed to meet the other two still coupled O₂ beings, whereby one O being rushing to meet one O₂ couple each, to form O₃ which is a new group consisting of three beings holding hands known as Ozone

Note, that O stands for atomic oxygen gas

O₂ stands for oxygen gas

O₃ stands for ozone gas

X-rays with a wavelength of 8.82 nm. Calculate the frequency of the x rays
krok68 [10]

Answer:

The wave with the wavelength of 8.82 nm have frequency of 0.340 × 10¹⁷ s⁻¹.

Explanation:

Given data:

Wavelength of x-ray = 8.82 nm

frequency of x-ray = ?

Solution:

speed = Wavelength × frequency

frequency = speed /  Wavelength

c = 3 × 10⁸ m/s

f = c/ λ

f = 3 × 10⁸ m/s /8.82 × 10⁻⁹m

f = 0.340 × 10¹⁷ s⁻¹

The wave with the wavelength of 8.82 nm have frequency of 0.340 × 10¹⁷ s⁻¹.
