The situation of a wave pulse is given as y=(0.8)/((4x+5t)+4) the amplitude and velocity of pulse are

Answer»

`0.2` units, `1.25` units along `-`ve x-axis
`0.2` units, `1.25` units along `+`ve x-axis
`0.4` units, `1.25` units along `-`ve x-axis
`0.4` units, `1.25` units along `+`ve x-axis

Solution :At amplitude , DISPLACEMENT is MAXIMUM i.e. At `x=0` , `t=0` . For some displacement
`4x+5t+4=`cons`tantimplies4dx+5dt=0`
`impliesv=(DX)/(DT)`
