the amount of diffraction depends on how close the width of the slit is to the wavelength, so light of different wavelengths different amounts for a give slit width, resulting in different values for theta

Where can I get a 300 lines/mm diffraction grating exactly like the one you used at 44 seconds into your video? My diffraction grating has 1000 lines/mm and it does not produce higher order image pairs like the one you used in your video. It would mean a lot to me to get the 300 lines/mm grating you used and show my Dad that is does indeed produce higher order image pairs as shown in your video.

I'm in the fifth grade at my school. We haven't talked about lasers or diffraction gratings yet. It's my Dad that bugs me about this stuff. At home we got some diffraction gratings that have 1000 lines/mm and a red laser pointer but it doesn't work. We only get 3 dots no matter what we try. We don't get higher order image pairs like you do in your video. So we are getting more diffraction gratings with less lines per mm. Yours has 300 lines/mm. In a few days we will be able to try this with 100, 300, and 600 lines/mm. It will mean a lot to my Dad to see the higher order image pairs in his lifetime.
