Question

Two thin slits with separation of .0250mm are placed over monochromatic orange laser light at 610.nm. What is the small angle measurement from the central maximum (zero degrees, inline with the source) to the first maximum

Answer 1

the small angle measurement from the central maximum is

Step-by-step explanation:

The computation of the small angle measurement is as follows:

The constructive interference condition is

`d \sin \theta = m \lambda \\\\Now \\\\\theta = sin^(-1) ((\lambda)/(d)) \\\\= sin^(-1)((610*10^(-9))/(0.0250*10^(-3)) )\\\\= 1.40^(\circ)`

hence the small angle measurement from the central maximum is
`1.40^(\circ)`
