When you shine a laser with unknown wavelength through adiffraction grating with 1000 slits/mm, you observe the m = 1bright fringe on the screen with an angle of 26 degrees away fromthe center of the grating.
What is the wavelength of your laser?
Plug in the relevant numbers to solve for your laserpointer photon wavelength in nanometers.
If the new diffraction bright fringe is at a LARGERangle than the diffraction bright fringe from the first grating, isthe new diffraction spacing larger or smaller than the olddiffraction line spacing?
Similarly, what if the new diffraction bright fringe isat a SMALLER angle?
