Questions and Answers

What is the phenomenon of resonance?

  • The phenomenon of a vibrating body influencing the frequency of another vibrating body
  • The phenomenon of a vibrating body influenced by another vibrating body at the same frequency (correct)
  • The phenomenon of a non-vibrating body influenced by a vibrating body
  • The phenomenon of a vibrating body influenced by another vibrating body at different frequencies

What is the equation to calculate the propagation velocity of waves?

  • v = λ + f
  • v = f - λ
  • v = f / λ
  • v = λf (correct)

What is the relationship between the speed of sound and the temperature of the laboratory?

  • The speed of sound decreases with increasing temperature
  • The speed of sound increases with decreasing temperature
  • The speed of sound is not affected by the temperature
  • The speed of sound increases with increasing temperature (correct)
