Are you looking for a way to spice up your physics lessons or experiments? Do you want to impress your students, friends, or family with a cool demonstration of the Doppler effect? If so, you might be interested in the Doppler Effect Demonstration Apparatus, a simple but effective device that can produce audible changes in frequency as you swing it around.
The Doppler effect is a phenomenon that occurs when the source or the observer of a sound wave is moving relative to each other. The frequency of the sound wave appears to increase or decrease depending on the direction of the motion. For example, when an ambulance is approaching you, the siren sounds higher than when it is moving away from you.
The Doppler Effect Demonstration Apparatus is a great way to illustrate this concept in a fun and interactive way. It consists of a 92dB buzzer attached to a nylon cord and a handle. The buzzer emits a constant tone when it is stationary, but when you spin it around, you can hear the pitch change as the buzzer moves closer or farther from your ears. The faster you spin it, the more noticeable the effect is.
Product Details
The Doppler Effect Demonstration Apparatus is made of durable and lightweight materials. The buzzer housing is constructed of rugged ABS plastic and has a simple on/off switch. The nylon cord is 2’8″ long and is attached to a sturdy ABS handle that is 8.5in long and 1in in diameter. The device comes with a 9V battery installed, so you can start using it right away.
The Doppler Effect Demonstration Apparatus is suitable for anyone who is interested in physics, acoustics, or sound waves. It can be used in classrooms, laboratories, or at home. It is a perfect tool for teachers, students, hobbyists, or enthusiasts who want to learn more about the Doppler effect or demonstrate it to others. It can also be used as a fun and educational toy for kids or adults who enjoy science experiments.
