The wavelength and frequency of a wave are related to one another by the speed of travel of the wave, which depends on the type of wave and the medium through which it is passing. Created by Khan Academy.

• Does your voice just stay in one frequency when you're speaking, or does it changes with every sound you make?
• The frequency changes while you speak because the sounds that compose words are a variety of frequencies.
• ngl i'm becoming a science nerd and i'm liking it
• how do I cook pizza at a school?
• by cooking one
• I'm in 6th grade!! This video doesn't Help AT ALL!

Edit; Why are all these people responding and some of these have nothing to do with what I said
• Don't worry to much about it, I'm in highschool and this ain't easy for me either, go through problems once just looking at the hints, they actually explain the concepts better sometimes and if you are still struggling with something specific, don't be ashamed to put out here in the questions.

• It says this is in Middle School physics - NGSS, what does NGSS mean?
• Next Generation Science Standards.
• could I theoretically cancel out someone else's voice using destructive interference
• Yes. If your wave is inverted to someone else's, it would cancel the wave out.
• What is a rope made out of
• Common natural fibres for rope are Manila hemp, hemp, linen, cotton, coir, jute, straw, and sisal. Synthetic fibres in use for rope-making include polypropylene, nylon, polyesters (e.g. PET, LCP, Vectran), polyethylene (e.g. Dyneema and Spectra), Aramids (e.g. Twaron, Technora and Kevlar) and acrylics (e.g. Dralon).
