Question

For a wavelength of 490 nm, a diffraction grating produces a bright fringe at an angle of 26°. For an unknown wavelength, the same grating produces a bright fringe at an angle of 36°. In both cases the bright fringes are of the same order m. What is the unknown wavelength?

$Bright fringe m (unknown wavelength) Bright fringe m (known wavelength) Central bright fringe (m- 0) Bright fringe m (known wavelength) Bright fringe m (unknown wavelength) Diffraction grating Screen$
