Does Wavelength Times Frequency Determine Speed of Light?

AI Thread Summary
The discussion centers on the relationship between wavelength, frequency, and the speed of light, confirming that speed equals wavelength multiplied by frequency. It addresses whether calling 'c' the speed of light is misleading, clarifying that it is acceptable since all forms of electromagnetic radiation travel at the same speed in a vacuum. Participants agree that referring to 'c' as the speed of light is a generic term, even though it could also apply to other forms of electromagnetic radiation like gamma or infrared. The conversation also touches on misconceptions about the speed of visible light compared to gamma rays, ultimately concluding that such comparisons are inaccurate. The thread emphasizes the consistency of the speed of electromagnetic radiation in a vacuum.

equals speed?

I only ask as I couldn't find a solid answer online.

Isn't calling C the speed of light in e=mc2 misleading as light is a specific part of the electromagnetic radiation spectrum.

Shouldn't C be the speed ot the electromagnetic radiation spectrum
 
Since all forms of electromagnetic radiation have the same speed in a vacuum, calling 'c' the speed of light is OK. Often all wavelengths, not just the visible, are referred to as 'light'.
 
Right so then there would also be no objection to calling C the speed of gamma, or speed of infrared?

Sure. No problem. All the same. Just calling it the 'speed of light' is more generic, though.

Is this true?
