The following solution is suggested to handle the subject “Green light has a frequency of about 6.00 x 10^14 s-1 . What is the energy…“. Let’s keep an eye on the content below!

Question “Green light has a frequency of about 6.00 x 10^14 s-1 . What is the energy…”

Answer

You can calculate the energy of a photon using Planck’s equation

Here

refers to the energy of photons

,

refers to Planck’s constant

, and

refers to the frequency of the photon photon

.

Wave equation provides the relationship between speed, frequency, and wavelength.

is the speed of light

and HTMLmedia_tag_10$ are the wavelengths of the photons. #media_tag_11$ represents the frequency.

Part 1

It is well known that the frequency media_tag_12$ is the green light. The

is the same.

Planck’s equation says:

Substitute

for

and

for Planck’s constant

.

Part 2

It is well-known that the wavelength of X-rays is

.

Since,

Therefore,

Planck’s equation says:

According to the wave equation

You can rewrite the equation as follows:

This frequency expression can be substituted in the Planck equation.

Substitute

to Planck’s constant

;

to

;

to

.

Ans Part 1

Part 1

Answer

is the energy of a photon with green light.

Conclusion

Above is the solution for “Green light has a frequency of about 6.00 x 10^14 s-1 . What is the energy…“. We hope that you find a good answer and gain the knowledge about this topic of science.
