A transverse waves is travelling in a string. Study following statement.
(i) Equation of the wave is equal to the shape of the string at an instant t. (ii) Equation of thhe wave is general equation for displacement of a particle of the string (iii) Equation of the wave must be sinusoidal equation (iv) Equation of the wave is an equation for displacement of the particle at one end only.correct statement are

Options

A. (i) and (ii)
B. (ii) and (iii)
C. (i) and (iii)
D. (ii) and (iv)

Answer

a

Explanation

At any instant `t`, the wave equation will express the variation of `y` with `x` which is equal to the shape of the string at an instant `t`.
