$\lambda\times\nu = c$ $\lambda$: wavelength of radiant energy (m) $\nu$: frequency of radiant energy (1/s) c: speed of light (m/s)
This question asks you to build a relationship between the wavelength ($\lambda$) and frequency ($\nu$) of radiant energy (electromagnetic radiation). Because they are inversely related, and all radiant energy travels at the same speed of light (c), the relationship is written as follows: $\lambda\times\nu = c$
