Maximum angle of diffraction can be 90°, i.e., θ = 90°.
λ = 5000 x 10-8 cm
∴ Grating element (a + b) =
For nth maxima , we find
(a + b) sin θ = nλ
Hence, 6 order will be visible.

This question is incomplete and cannot be answered as it is missing important information. The wavelength of incident radiation alone does not provide enough information to determine the number of orders visible. The type of grating, the spacing of the lines, and the angle of incidence are all necessary parameters for calculating the number of orders visible.
