Introduction

Wave is an oscillation accompanied by a transfer of energy that travels through medium (space or mass)

Waves consist, instead, of oscillations or vibrations (of a physical quantity), around almost fixed locations

This simulation is on transverse wave where disturbance creates oscillations that are perpendicular to the propagation of energy transfer.

The equation for wave is A sin ( wt +kx + ϕ)

where

A is the maximum amplitude of the wave, maximum distance from the highest point of the disturbance in the medium (the crest) to the equilibrium point during one wave cycle.

w is is the angular frequency

t is time

k is is the wavenumber

x is the position

ϕ is the is the phase constant

concepts illustrated in the simulations include

T is the time for one complete cycle of an oscillation of a wave

f is the number of periods per unit time (per second) and is related by T = 1/f

λ is the wavelength

v is the velocity of the wave travelling and is related by v= f λ

vtmax is the maximum transverse velocity of the wave particle that occurs at the displacement d =0.
