Homework Statement
A single slit forms a diffraction pattern, with the first minimum at an angle of 40 from the central maximum. Monochromatic light of 410 nm wavelength is used. The same slit, illuminated by a different monochromatic light source, produces a diffraction pattern with the second minimum at a 60 angle from the central maximum. (Remember to convert degrees to radians – Recall: 2πrad=〖360〗^0.)
A) What is the width of the slit?
a. 587 nm b. 103 nm c. 1170 nm
B) What is the wavelength of the second light source?
a. 587 nm b. 307 nm c. 615 nm
C) If the screen is placed 1 meter away, what is the width of the central maximum for the 410 nm light source?
a. 0.70 m b. 1.4 m c. 2.
