The following is a standard question found in many textbooks:
Question: Light of wavelength 560 nm is incident on a slit of width 0.354 mm. The observing screen is placed 1.5 m from the slit.
A- Find the positions of the first dark fringes and the width of the central bright fringe.
I need help to solve the above question and provide a ray tracing of the single-slit experiment to verify your answer is true.
An electron moving at 3.8 x 103 m/s in a 1.3 T magnetic field experiences a magnetic force of 1.75 x 10-16 N. What angle (in degrees, between 0 and 90°) does the velocity of the electron make with the magnetic field
