Determine the wavelength of radiation with a frequency of 1.50x10^13s^-1. Does this radiation have a longer or shorter wavelength than red light?

I don't want just the answer i would love an explanation please :)

Recall the equation $$v = \frac{ d }{ t }$$ similarly we have a relationship for wavelength and frequency which follows $$c = \lambda f$$ where c is the speed of light, lambda is the wavelength and f is frequency.

So how would I plug in the information to the equation? my teacher did not explain anything and just gave us work and a quiz tomorrow

kingbowzer · Answer

c is a constant (speed of light), and it appears you are given frequency.  @Astrophysics provided an equation that relates these two quantities (they are proportional with proportionality lambda).  @Astrophysics also provided motivation for unit analysis.
