More slits make the bright maxima sharper and brighter — the principle behind spectrometers that split light into precise spectral lines.

Maxima atd·sinθ = mλ

Governing equation

d sin θ = mλ : 30 sin θ = m \cdot 20, θ_{1} = 41. 8^{\circ}

Reading this result: The bright maxima stay locked where d·sinθ = mλ — fixed by spacing and wavelength, not slit count — but with 5 slits each principal peak is about 5× narrower and far more intense, which is how a grating resolves fine spectral lines.

About this simulation

The full Diffraction Grating tool models a telescope with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
