Please Help Upon using Thomas Young’s double-slit experiment to obtain measurements, the following data were obtained. Use these data to determine the wavelength of light being used to create the interference pattern. Do this using three different methods.

The angle to the eighth maximum is 1.12°.

The distance from the slits to the screen is 302.0 cm.

The distance from the central maximum to the fifth minimum is 3.33 cm.

The distance between the slits is 0.000250 m.

The 3 equations I used were 1). d sin θ_m =(m)λ 2). delta x =λL/d and 3.) d(x_n)/L=(n-1/2)λ
but all my answers are different.
DID I DO SOMETHING WRONG
