Using Monochromatic Light of 410 Nm Wavelength,a Single Thin Slit

Multiple Choice

Using monochromatic light of 410 nm wavelength,a single thin slit forms a diffraction pattern,with the first minimum at an angle of 40.0° from central maximum.The same slit,when illuminated by a new monochromatic light source,produces a diffraction pattern with the second minimum at a 60.0° angle from the central maximum.What is the wavelength of this new light?

A) 276 nm
B) 293 nm
C) 309 nm
D) 326 nm
E) 342 nm
