# What waves look like?

In high school we have always been taught that wave looks figure $$A$$ and from there we have learnt amplitude,frequency etc of waves. But in a lot of books, waves are represented by the second figure and are often told waves look like this. I know that the circumstances are wavefronts here but they are not waves. That's why i can't think of wavefront and wave as the same. How can i think of these $$2$$ samely?

• Both work for water waves but a light wave is made of photons, coherent in speed, frequency and phase. Apr 24 at 17:39
