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

B) The energy is proportional to the mass of the atom undergoing fission.
C) The energy is derived from the light that is emitted when the atom splits.
D) The energy equation does not apply towards fission, only fusion.
E) none of the above
