What is the energy photon with a frequency of 2.22 x 10^14 1/s ?

1.47 x 10⁻¹⁹J

Explanation:

Given parameters;

Frequency of wave  = 2.22 x 10¹⁴/s

Unknown:

Energy of the photon = ?

Solution:

The energy of a photon can be mathematically derived using the expression below;

        E = hf

  E is the energy

 h is the Planck's constant = 6.63 x 10⁻³⁴m²kg/s

 f is the frequency  

Insert the parameters and solve;

 E = 6.63 x 10⁻³⁴m²kg/s x  2.22 x 10¹⁴/s  

 E = 14.7 x 10⁻²⁰J or 1.47 x 10⁻¹⁹J

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
