Velocity of Sound: Resonance in Closed Air Columns

Play an AI-generated podcast conversation about this lesson

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)
