Review on Diffraction Grating Slide Linear Lines Pack by Shawn Xayamonty

I teach science and this is a great way to introduce diffraction and double and multiple slit experiments. If you also buy flashlights that can emit both laser and white light, you can demonstrate the multi-slit effect with the laser, as well as a beautiful rainbow that will catch the attention of younger students. If you have lasers of different colors you can show that the angle of diffraction depends on the wavelength, which in turn explains the rainbow. Provides excellent learning material.
