## Homework Statement

The following data was obtained via the double slit experiment:

angle to the eighth maximum = 1.12 degrees

distance from slits to screen = 302cm = 3.02m

distance from first to fifth mimum = 2.95cm

distance between slits = 0.00025m

find the wavelength.

## Homework Equations

supposed to use this equation to find wavelength:

x

_{n}/L=(n-0.5)([itex]\lambda[/itex]/d)

or

x

_{m}/L=(m)([itex]\lambda[/itex]/d)

## The Attempt at a Solution

problem is, there's no given value for x

_{m}or x

_{n}

how can i get this value?

(oh, and i specifically have to use the equation listed above)
