Scientific experiment case with laser pointer
Laser Pointers are often used as laboratory tools for scientific research in schools and are widely used. They have their own characteristics in the classroom. In physics, the existing experimental light sources on optical displays are not ideal: large, complex, and difficult to tune; Although the initial force is very strong, the Angle of light energy utilization is not high; The lighting on the equipment was very rough, very bad, not bright at all. These problems can only be seen in dark Spaces, but with the use of lasers, they were significantly improved.

A small laser pointer can take the place of polarization and light source. Laser pointer also play an important role in producing polarized light. Or he wasn't used to being in a classroom with transparent tobacco numbers, with tar pans about 1 mm fixed to the bottom so he could store them or drop a few drops in a teapot. If you want to boil milk, note that the liquid "mirror" image can go right through the center of the circle. As you can see, three beams of light pass through the center of a laser in a circle. When you change the Angle of the head with feathers, you also change the introduction of polarized light, just the laser guidance, polarizer or Nico theory as the analyzer to explain the problem, which not only saves the demonstration equipment, but also reduces the team's time.
