Answer:

In order to get more orders of spectra from θ = 0 to θ = 90 for a given wavelength, the grating element d must be increased i.e. Less number of lines per unit length be ruled on diffraction grating.

Answer:

For obtaining more orders of spectra from θ = 0 to θ = 90 for a given wavelength, the grating element d must be increased. It means that there are less number of lines per unit length be ruled on diffraction grating.

Explanation:

Diffraction deals with various phenomena which occur when a wave encounters an obstacle or opening.

Diffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle.

For obtaining more orders of spectra from θ = 0 to θ = 90 for a given wavelength, the grating element d must be increased. It means that there are less number of lines per unit length be ruled on diffraction grating.

Mathematically,

d \sin \theta=n \lambda
