Radiation in the ultraviolet region of the electromagnetic spectrum is quite energetic. It is this radiation that causes dyes to
N76 [4]

The  energy of photon in kJ/mol is 329kJ/mol.

Wavelength of radiation is 370nm. The frequency of given wavelength is

            ν = c / λ

            ν = 3×10^8 / 370×10^-9

            ν = 8.11 × 10^14 s^-1

      Now the energy of photon is:

             E = hν

             E = 6.63×10^-34  J.s/photon × 8.11×10^14s^-1

             E = 5.41× 10^-19  J/photon

         To find in mole

              E = 5.41× 10^-19 × 6.022×10^23

               E = 3.29 ×10^ 5 J/mol

   So, the energy of mole of photon is equal to 329 kJ/mol.

German physicist Werner Heisenberg related the uncertainty of an object's position ( Δ x ) to the uncertainty in its velocity (
timama [110]

According to the information given, the Heisenberg uncertainty principle would be given by the relationship

\Delta x \Delta v \geq \frac{h}{4\pi m}

Here,

h = Planck's constant

\Delta v = Uncertainty in velocity of object

\Delta x = Uncertainty in position of object

m = Mass of object

Rearranging to find the position

\Delta x \geq \frac{h}{4\pi m\Delta v}

Replacing with our values we have,

\Delta x \geq \frac{6.625*10^{-34}m^2\cdot kg/s}{4\pi (9.1*10^{-31}kg)(0.01*10^6m/s)}

\Delta x \geq 5.79*10^{-9}m

Therefore the uncertainty in position of electron is 5.79*10^{-9}m

trapecia [35]
<h2>What are spooky rays? :Spooky rays are Halloween; Spooky mystic background light beams rays.</h2>

<h2>How was spooky rays discovered; In 1895,a German Engineer Wilhelm Röntgen, was experimenting with making cathode rays .His device was blacked out.But he noticed a piece of cardboard painted with barium platinocyanide flouresced when it was placed near the cathode ray tube.</h2>

<h2>How are they related to visible light?: This occurs when two particles are inextricably linked.</h2>
