Hi Yeeling, the contact that I forwarded you teaches Chem but not Physics. I have no experience with Physics tutor so far. Cheers.

Hi all

can someone provide opinion on this matter.
For a transverse wave travelling to the right, at a particular instant, what is the speed of the particles at the crest, the centre position and at the trough when compare to each other? Which is faster -- Vcrest, Vcentre & Vtrough?
Thank you

Hi

May i have some advice on Science tuition, please.
Is it necessary to start Science tuition in Sec 1? Better to have home tutor or group class at tuition centre? I stay in Clementi. Is there any good Science tuition centre in Clementi, Jurong East or Bukit Batok area?

TIA.

You chose an interesting place to pose your question. In case you have not gotten your answer, hope that my explanation below helps.

Particles at the crest and trough are momentarily at rest
i.e Vcrest = Vtrough = 0

Vcentre is highest compared to all other positions. However, particles at centre may have opposite velocity if they are 180 degrees out of phase with one another.
