Velocity of sound in air with Universal Counter

Principle

The velocity of sound in air is determined by measurement of sound travel times across known distances.

Benefits

• Perfect as demonstration and student experiment
• Easy setup and fast procedure
• Easy entry into the topic of error calculation possible

Tasks

Determine the sound velocity in air for different distances between sound source and microphone.

Learning objectives

• Wave propagation
• Longitudinal wave
• Air pressure variation
