China Wholesale Jolly balance Manufacturers – LMEC-13 Comprehensive Experiments on Rotating Liquid – Labor Detail:
Experiments
1. Measure gravity acceleration g using two methods:
(1) Measure the height difference between the highest and the lowest points of the surface of rotating liquid, then calculate gravity acceleration g.
(2) Laser beam incident parallel to the rotation axis to measure surface slope, then calculate gravity acceleration g.
2. Verify the relationship between focal length f and rotational period t according to the parabolic equation.
3. Study concave mirror imaging of rotating liquid surface.
