Worked practice questions

Points on a standing wave where the amplitude is zero are called:

  1. Necks
  2. Nails
  3. Nodes
  4. Nooks
Show answer and solution

Correct answer: C. Nodes

1. A standing wave has fixed points of no motion and of maximum motion. 2. The still points have their own name. 3. The points at which the amplitude is zero are nodes. 4. The points at which the amplitude is largest are antinodes. _Source: syllabus Physics Part II, Ch 14 'Waves'_

The lowest possible natural frequency of a system is called its:

  1. Fundamental motto
  2. Fundamental model
  3. Fundamental module
  4. Fundamental mode
Show answer and solution

Correct answer: D. Fundamental mode

1. A vibrating system has a whole series of natural frequencies. 2. The lowest of them is singled out. 3. The lowest possible natural frequency is called the fundamental mode. 4. It is also called the first harmonic. _Source: syllabus Physics Part II, Ch 14 'Waves'_

Transverse waves can propagate only in media that can sustain which stress?

  1. Shearing stress
  2. Shedding stress
  3. Shielding stress
  4. Shifting stress
Show answer and solution

Correct answer: A. Shearing stress

1. A transverse wave needs the medium to resist sideways deformation. 2. Only some states of matter can do that. 3. Transverse waves propagate only in media which can sustain shearing stress. 4. That means solids and not fluids. _Source: syllabus Physics Part II, Ch 14 'Waves'_
