What is the frequency of radiation whose wavelength is 2.51 x 10 -7m?​

Chemistry

The frequency of radiation : 1.2 x 10¹⁵ Hz

<h3>Further explanation </h3>

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

\large{\boxed{\bold{E\:=\:h\:.\:f}}}

Where

h = Planck's constant (6,626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves

<h3>f = c / λ </h3>

c = speed of light

= 3.10⁸  m/s

λ = wavelength

Wavelength-λ is 2.51 x 10⁻⁷m

The frequency :

\tt f=\dfrac{3.10^8}{2.51\times 10^{-7}}=1.2\times 10^{15}

Who is Gilbert Newton lewis ​
skelet666 [1.2K]

Gilbert N. Lewis (1875-1946) was an American physical chemist.  

His work with heavy water and resources were adapted by Ernest Lawrence in the development of the cyclotron.

 

SCIENTIFIC CONTRIBUTIONS

Lewis made many contributions to science. He was nominated for the Nobel Prize 41 times, though he was never awarded the prize.

He discovered covalent bonds and electron pairs. He worked with isotope separation, and became the first person to purify a sample of heavy water. The heavy water was later used as projectiles in Lawrence’s 27-inch cyclotron.  

He also made contributions in ideas on relativity and acid-base reactions and coined the term “photon” as the smallest unit of light.

How waves affect matter at the macroscopic and particle levels.
Rus_ich [418]
In a macroscopic object, each particles wave is being absorbed and combined with the waves of the other particles to create one wave for the entire object. Since this object is able to be seen, the wave function immediately collapses.

Anytime you possess anykind of information about the world around us, some wave, somewhere function collapses.

In short, if we can see the object, then it has no wave function.
