In a ruby laser, an electron jumps from a higher energy level to a lower one. if the energy difference between the two levels is
Vaselesa [24]

The wavelength of the emitted photon is(\lambda)= 690nm

<h3>How can we calculate the wavelength of the emitted photon?</h3>

To calculate the wavelength of the photon we are using the formula,

\triangle E= \frac{h\times c}{\lambda}

Or,\lambda= \frac{h\times c}{\triangle E}

We are given here,

\triangle E= The energy difference between the two levels = 1. 8 ev= 1.8\times 1.6 \times 10^{-19} C.

h= Planck constant = 6.626\times 10^{-34} Js.

c= speed of light = 3\times10^8 m/s.

We have to find the wavelength of the emitted photon =\lambda m.

Therefore, we substitute the known parameters in the above equation, we can find that,

\lambda= \frac{h\times c}{\triangle E}

Or,\lambda= \frac{6.626\times 10^{-34}\times 3\times 10^8}{1.8\times 1.6 \times 10^{-19}}

Or,\lambda= 690\times 10^{-9} m

Or,\lambda=690 nm.

From the above calculation we can conclude that the wavelength of the emitted photon is 690nm.

Odina walked down the hall at school from the cafeteria to the band room, a distance of 100.0m. A class of physics students
Nata [24]

Find distance she traveled:

100m -25m = 75m


58 seconds / 2 second intervals = 29

29 x 2.6m = 75.4 meters total.


if the distance wasn’t rounded the statement was False.


Answer: False
