what happen when monochromatic light irradiated on reflective grating? where is the light will be? what is the pattern like? thank you very much!
best wishes!

Hint: Use Bragg's Law.

still no idea! I am stupid!

I am loathe to simply give you the answer, when there are ample sources online to figure it out for yourself.

It would do you no favors; you are better off learning how to answer basic questions such as this on your own.

If you are stuck, show us exactly where, and why and we will be more obliged to help!

When monochromatic light is irradiated on a reflective grating, it will diffract into various angles and form a diffraction pattern. The light will be dispersed into different orders, with the highest intensity at the central, zeroth order and decreasing intensities at the higher orders. The exact pattern will depend on the spacing between the grating lines and the wavelength of the light. In general, the pattern will consist of bright and dark fringes, with the brightest fringe in the center and the fringes becoming less and less intense as they move away from the center. This phenomenon is known as diffraction and is a result of the light waves interacting with the grating structure. The diffraction pattern can be used to measure the wavelength of the monochromatic light and to study the properties of the grating itself. I hope this helps! Best wishes to you as well.
