Llus Light passes through a single slit of
width 8.77 x 10-6 m. The second (m = 2)
diffraction minimum occurs at an angle
of 5.62º. What is the wavelength of the
light IN NANOMETERS?
[?] nm
Hint: The answer will be between 400 and 700 nm.
Remember: nano means 10-9

3. a particle with initial velocity v⃗ 0=(5.85×103m/s)j^ enters a region of uniform electric and magnetic fields. the magnetic field in the region is b⃗ =−(1.35t)k^. you can ignore the weight of the particle. a. calculate the magnitude of the electric field in the region if the particle is to pass through undeflected, for a particle of charge +0.640 nc.
