For y = a sin(kx - wt + phi), the wave travels toward

  1. positive x axis
  2. negative x axis
  3. the y axis
  4. no direction
Show answer and solution

Correct answer: A. positive x axis

Keeping kx - wt constant requires x to grow with time, so the wave moves along positive x.

In the wave equation, k is called the

  1. angular frequency
  2. angular wave number
  3. wave amplitude
  4. phase constant
Show answer and solution

Correct answer: B. angular wave number

In y = a sin(kx - wt + phi), k is the angular wave number and w is the angular frequency.

Which of these media has the highest speed of sound?

  1. Air at 20 C
  2. Seawater
  3. Steel rod
  4. Hydrogen
Show answer and solution

Correct answer: C. Steel rod

Sound travels fastest in solids, and steel at about 5941 m/s exceeds liquids and gases listed.
