Diffraction of laser light through a grating onto a semicircular screen.
Diffraction of laser light through a grating onto a semicircular screen.
A monochromatic laser beam with a wavelength of \(\lambda = 600\text{ nm}\) is incident perpendicularly on a diffraction grating ruled with \(300\text{ lines/mm}\). A large semicircular screen is positioned behind the grating, centered on the point of incidence, to capture all transmitted diffraction maxima. What is the total number of bright interference fringes (maxima) that can be observed on the screen?
