1. The problem statement, all variables and given/known data
A single slit is illuminated with a helium-neon laser whose wavelength is 633 nm. If the slit width is 2.2 x 10 e-5 m, calculate the position of the third maximum in degrees
2. Relevant equations
Sin Theta(m) = (m + 0.5) Lambda/w
3. The attempt at a solution
Sin Theta(3) = (3 + 0.5)(633 x 10 e-9)/2.2 x 10 e-5
=(3.5)(633 x 10 e-9)/2.2 x 10 e-5
=0.1
Theta(3) = sin-1(0.1)
=5.7 degrees
Therefore, the position of the third maximum is at 5.7 degrees
Does this seem right to anybody?
