concept???

what do u understand by f(t-x/v)????(in case of waves)

write anything ,what u can extract from this.

this is the eqn of wave.... wrt to the particle at x=0 as time passes..

i mean this eqn gives the position or displacement of the point x=0 as time passes.

and also,,, the wave is travelling in the positive x-direction.

the point at o will move in which direction????

areh see all will move towards +ve direction only. its like we are displacing graph to the right

i m asking about the point???

skygirl ·

the point will not move anywhere!

it is the wave that travels..

all particles jus travel up and down ..

there is only y-displacement..

no x-displacement.

+y or -y ???

u guys r not giving the answer at one go???need some revision

Grandmaster ·

the info provided just shows that its a function (possiblly),a function of a wave that has dependence on t and x.we even cannot predict whther this wave is even sinusoidal or not(atleast with the given info)

the satisgying condition for a funtion to be a wave (atleast in our syllabus is

(d2y/dx) / (d2y/dt) = k(a constant)

suppose f is sin then write your answer

chemistry organic ·

ive already wrote in case of waves

Grandmaster ·

oh yeah,then if it is a sin() then i will say its a sine function having dependence on t and x,we still don t know whther its alinear ,quadratic or which relation

y=sin(t-x/v)

now tell.

haan ab kuch sahi hai(and within our course)

this is a eqn of a wave that which propagates along the x direction and whose particles vibrate in shm in the y direction

(don't ask in which x direction it propagates as that is assumption based)

dont u think all people above told it will travel in +ve x.....so it must correct.....or u still differ

1
chemistry organic ·

or tel me wat assumtionn for it to travel in +ve x axis???
