Science Buddies: Measuring Vibrational Frequency With Light

Curated by ACT

Strike a key on the piano, and you hear the string vibrating. Just about any object vibrates when it's knocked, but how much and how fast? This project helps you find out. You'll build a simple light-sensing circuit for measuring the frequency of vibrating springs.
