Oct 5, 2021 · The speed of light will always be 3.00x10^8 m/s, assuming the light is travelling through air or in a vacuum. The values for speed of light in the air and in a vacuum are slightly different, but both round to 3.00x10^8.

Oct 21, 2020 · The value 2.998 x 10^8 m/s is the most precise so although it is easy to remember 3.0 x 10^8, if the grading is very picky, it is likely best to go with the figure closest to its exact value, that being the 2.998 x 10^8 representation of the speed of light.
Planck Constant and Speed of Light. - CHEMISTRY COMMUNITY
Oct 7, 2024 · Second, I am under the assumption that c, the speed of light, at 3.00x10^8m.s^-1, is the speed of light in a vacuum. Why do we use this value? Are we simply calculating the maximum possible energy a photon can have or are all light experiments done under the conditions of a vacuum.
Speed of Light - CHEMISTRY COMMUNITY - University of …
Oct 14, 2018 · The speed of light is constant in vacuum, and the speed is 3*10^8 m*s^-1, which would also be generally used in solving general problems. However, the speed would actually be a little bit slower when there is air, whereas we generally ignore this difference between the idea and the fact in our calculations for this course.

Oct 15, 2019 · The speed of light will always be a constant and is labeled in equations as the variable "c". It is somewhere around 3.0 X 10^8 m/s. On exams, make sure to use the exact number for the speed of light that is given to you on the equation sheet of the exam. This will help you with getting the right number of sig figs and prevent any rounding errors.
Is c always the speed of light? - CHEMISTRY COMMUNITY
Oct 26, 2020 · In reference to the equation , the variable c should always be representative of the speed of light. The speed of light, c, is generally approximated to 3.00*10^8 m/s, however, more accurately is 2.99792*10^8 m/s.
Speed of light wavelength equation - CHEMISTRY COMMUNITY
Dec 9, 2017 · Re: Speed of light wavelength equation Post by madisonhanson1b » Mon Apr 09, 2018 8:57 pm Most commonly I think we have been using the equation in the form wavelength= c (3.0 x 10^8)/ frequency to solve for the wavelength.
Speed of light value - CHEMISTRY COMMUNITY - University of …
Oct 11, 2021 · For the speed of light, should we use 3 x 10^8 m/s or be more precise and use 2.998 x 10^8 because I know that in lectures we use 3 x 10^8 m/s but in the textbook they used the other value. Top Amanda Pineda 3H
Speed of Light Equation - CHEMISTRY COMMUNITY
Oct 17, 2020 · I believe the speed of light and it's related equations should remain constant in a vacuum but does change when travelling through a medium (like air, water, etc.). For our class, I believe we'll only work with the assumption that light is travelling in a vacuum and in any non-vacuum cases, he will most likely provide us with the correct speed ...

Oct 13, 2017 · Re: Speed of Light Constant Post by Lily Guo 1D » Mon Oct 16, 2017 4:58 am 2.998 x 10^8 m/s is more accurate, but Professor Lavelle uses 3.00 x 10^8 in his lecture slides and example problems, so I don't think using 3.00 x 10^8 would be an issue.
