Two electromagnetic waves P and Q travel in a vacuum and the ratio of their wavelengths is 1x10^8
Which row in the table shows the ratio of their speeds, the ratio of their frequencies, and
identifies the possible natures of P and Q?
I'll attach the table below
- v=f lambda
By rearranging over and over ratio formulas involving frequency, speed and wavelength, I came up with the equation:
This led me to take into account only rows A, B, E, and F... but I can't really understand which one of these is the right one.
