How does a shorter wavelength affect the frequency of a wave?

The product of (wavelength) x (frequency) is always the same number ... the speed of the wave. So if one of them decreases, the other one must increase in order to keep the product the same. Shorter wavelength means higher frequency. 

This is what i found on google “lithium and sulfide can react together to form litium sulfide(li2s). when lithium sulfide hydrolyses(breaks down) in air, it releases hydrogen sulfide which is characteristized by a rotten egg odor.” i hope this you for what your looking for

Alinear relationship would look like a straight line on the graph. it could have a positive negative or 0 slope. so it could be a line potentially going in any direction but it must be perfectly straight.
