प्रश्न
Answer in brief:
A wave is represented by an equation y = A sin (Bx + Ct). Given that the constants A, B and C are positive, can you tell in which direction the wave is moving?
उत्तर
The equation of the wave is y = A sin (Bx + Ct).
The constants A, B, and C are positive.
When the variable of the equation is (Bx + Ct)
then the wave must be moving in the negative x-direction.
