Question

a transverse wave is shown. what is the amplitude of this wave? 1.3 cm 2.1 cm 2.6 cm 4.2 cm

Explanation:

Step1: Recall the definition of amplitude

Amplitude is the maximum displacement from the equilibrium position.

Step2: Analyze the given value

The total vertical distance from the bottom - most point to the top - most point of the wave is \(4.2\) cm. Since amplitude \(A=\frac{\text{total vertical distance}}{2}\).

Step3: Calculate the amplitude

Substitute the value: \(A = \frac{4.2}{2}=2.1\) cm.

Answer:

2.1 cm
