Read full descriptionHide full description
Diffraction Grating Calculator is a physics/math calculator that calculates the angles of diffracted orders of monochromatic light when shone on a reflective diffraction grating. Features: - Instant calculation. - Results are copyable to other apps. - Formulas are included as reference. - Supports up to 16 decimal places. - Supports various units for each input. - Works seamlessly on both iPhone and iPad. - Lightweight, compact app optimized for everyday use. - Ad-free and built with privacy in mind. In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams traveling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element. Because of this, gratings are commonly used in monochromators and spectrometers. A diffraction grating is a material that contains a large number of parallel slits separated by a distance (d). This periodic separation of slits is usually on the order of micrometers. Because this distance is on the order of the wavelength of light, when light waves pass through the grating, the slits are able to cause constructive and destructive interference among the light waves. The waves will constructively interfere if the angle of reflection delays one of the waves by a whole wavelength. Diffraction grating equation: m * Ī» = a * sin(Īøm) Where: m: The order number of the diffracted image, m = 1,2,3 ... Īø: Grating angle, in radians a: Grating Spacing, in lines per meter Ī»: Wavelength, in meters Thanks for your support and do visit nitrio.com for more apps for your iOS devices.

Verdict
The clearest difference is price: VisualTimer byNSDev at Free against Diffraction Grating Calculator's $2.99. Diffraction Grating Calculator's advantage is device support and iOS requirement (13 vs 17). On in-app purchases there is nothing between them.
