Hydrogen’s emission spectrum includes a line of violet light that has a frequency of 7.31 * 10^14 Hz. What is the energy (in joules) a photon of the violet light?

Hydrogens Emission Spectrum Includes A Line Of Violet Light That Has A Frequency Of 731 1014 Hz What Is The Energy In Joules A Photon Of The Violet Light class=

Sagot :

Explanation:

The energy of a photon of the violet light can be obtained as follows:

[tex]E\text{ = h x f}[/tex]

E = energy

h = Plank's constant

f = frequency

-------

Data provided:

f = 7.31x10^14 Hz

--

Data needed:

h = 6.63x10^-34 Js

So, E = h x f = 6.63x10^-34 Js x 7.31x10^14 Hz = 4.85x10^-19 J

Answer: 4.84x10^-19 J (nearest value)
