Light of wavelength 618.0 nm 618.0 nm is incident on a narrow slit. The diffraction pattern is viewed on a screen 84.5 cm 84.5 cm from the slit. The distance on the screen between the second order minimum and the central maximum is 1.25 cm 1.25 cm . What is the width a a of the slit in micrometers (μm)?

83.55 μm

Explanation:

In a single slit experiment, the distance (on the screen), y, between the central maximum and the minimum of order, m, is given as:

y = * λ

where λ = wavelength

a = width of slit

d = distance between slit and screen

To get the width of the slit, we make a the subject of formula:

a = (mλd)/y

(All units of length are in meters)

a = 83.55 μm

porque la cantidad de gases de efecto invernadero alcanzó un nuevo máximo sin precedentes, causando daños muy graves a esta, por eso es importante monitorearla, para controlar el porcentaje de daños que esta causa y poder reducirlo o mantenerlo.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
