When anything occurs in a periodic manner, it means that the events (like waves . . .) occur one after the other repeatedly, in a regular manner.
I think you meant to say change but if so its because the weather is changing so are the nature things.
Saying "wave model of light" emphasizes that light exhibits wave-like behavior in certain situations, such as interference and diffraction, but can also display particle-like behavior in other situations. This acknowledges the dual nature of light as both a wave and a particle.
say "/wave"
I would rather say that light IS a wave, not that it HAS a wave. It is a type of electromagnetic wave.

Clarify the question first. Draw a diagram... What is meant by "distance from crest to trough" ? If you see that it should say "diagonal distance" the diagram then makes sense and its solution becomes obvious. - RogerC
I think it really depends on what you need. The wave doesn't say its meant for acne or anything so if you're just looking for a daily cleanser, get that, but if you're having problems with blackheads, I'd say go for the Eraser. I prefer Cellnique Skin Action Sebum Gel!
Wave is 'nami' in Japanese, as in 'tsunami' (tidal wave).
When we say that a wave is an energy transport phenomenon, we mean that a wave propagates through a medium by transferring energy from one point to another without permanently displacing the medium itself. This energy transfer occurs via the oscillation of particles or fields in the medium, allowing the wave to carry information and energy over distances.
"what I meant to say" is 'ce que je voulais dire, ...' in French.
Nothing, they just waved.
go up to her and say hi and walk off and if she stops you from walking away then maybe its meant to be <3
