NEET Physics Transverse & Longitudinal Waves MCQ Question
Which of the following combinations correctly describe the characteristics of stationary waves in a stretched string fixed at both ends?
Nodes are points of zero amplitude; Antinodes are points of maximum amplitude; Distance between nodes is λ/2.
All points oscillate in phase; The amplitude is constant across the string; The distance between antinodes is λ.
The frequency is the same at all points; Antinodes are at the ends of the string; Nodes are spaced λ apart.
The wavelength is determined by the string length; There are only even harmonics present; The amplitude varies linearly.
Correct Answer
Detailed Explanation
Stationary waves on a string fixed at both ends have nodes where the amplitude is zero and antinodes where the amplitude is maximum. The distance between adjacent nodes is indeed λ/2, as stated in the NCERT context.
