Question

A wave pulse moving to the right along the x-axis is represented by the wave function y(x,t)=2.0(x−3.0t)2+1 , where x and y are in centimeters and t is in seconds. (The maximum pulse height is defined as maximum displacement along y-axis). Then

Solution

The correct options are
B

The maximum pulse height is constant with time


C

The speed of the pulse is 3.0 cm/s


The maximum pulse height is 2.0 cm, when x - 3.0t = 0. It is constant.
Speed of the pulse = coefficient of tcoefficient of x=3.0 cm/s
