# A Wave is Represented by an Equation Y = C 1 Sin ( C 2 X + C 3 T ) in Which Direction is the Wave Going? Assume that C 1 , C 2 C 3 Are All Positive. - Physics

A wave is represented by an equation $y = c_1 \sin \left( c_2 x + c_3 t \right)$ In which direction is the wave going? Assume that $c_1 , c_2$ $c_3$ are all positive.

#### Solution

Equation of the wave is $y = c_1 \sin \left( c_2 x + c_3 t \right)$
When the variable of the equation is (c2x + c3t), then the wave must be moving in the negative x-axis with time t.
