(a) State Ampere's Law.
(b) The figure shows a toroid with N total turns and a current I . Apply Ampere's Law to find the magnitude of the magnetic field inside the toroid and at a distance r from the axis of the toroid. [Make sure you draw a diagram to show the Amperian loop.]
(c) Apply Ampere's Law to find the magnetic field around an innitely long straight wire with current I.
The absorption spectrum of an atom consists of the wavelengths 200 nm, 300 nm, and 500 nm. What wavelengths are seen in the atom's emission spectrum?
