Through the optical lever amplification effect, can easily make Vibration of a tuning fork Dynamic phenomenon.
- Base: iron (material) with size 330x320x30 mm
- Tuning Fork: 256Hz, with 2cm diameter reflector, with resonance box and hammer
- Projection whiteboard: 325 x300 x 5 mm
- 2x Metal Stands on which the laser light source and the motor-rotating scanning mirror can be installed:
- On the first one (near the projection whiteboard) the laser light source can be installed (the angle of the laser can be adjusted both horizontal and vertical so that can aim at the mirror/deflector on the tuning fork)
- On the other one (at the opposite side of the projection whiteboard) the motor-rotating scanning mirror can be installed (with an adjustable motor speed knot)
