The sketched graph above represents a progressive wave moving from the left to the right. The period of the wave is 0.125s.
Determine the values of the amplitude and wavelength, respectively, of the wave.
Attached Figure / Diagram
A
8 cm; 27 cm
B
8 cm; 9 cm
C
4 cm; 9 cm
D
16 cm; 27 cm
Verified Correct Answer: B.
Physical Principles & Numerical Solution
Amplitude = 16cm/2 = 8cm ( displacement from mean position)
3\(\lambda\) = 27cm
\(\lambda\) = \(\frac{27}{3}\) = 9cm
Therefore, amplitude(A) = 8cm and \(\lambda\) = 9cm
