### Speed of light.

Will we always consider the speed of light as a constant?

Yes, I believe so! The speed of light (c) can be set equal to 3.00x10^8 m/s.

Yes - I believe at this point we will consider the speed of light/radiation as a constant because there are no changing mediums in the problems we are dealing with.

yes and it might be one of the constants listed on the test sheets

### Re: Speed of light.

The speed of light is considered to be constant for our purposes in chemistry, but this is only a postulate since it has not been proved.

Yes we consider the speed of light in a vacuum to be a constant that we consider c

The speed of light will usually always be given as a constant when doing problems.

What is the exact value for the speed of light and how was this number calculated?

Yes, I believe that Lavelle specifically stated the c= speed of light is always a constant. Atleast in this class.

### Re: Speed of light.

Speed of light is a constant depending on the medium it travels through. The "c" speed of light constant indicates the speed of light in a vacuum.

Yes, we will consider the speed of light as a constant that can be expressed as 3.00 x 10^8 m/s^-1.
