A soap film (n = 1.33) is formed in a loop of wire that is mounted vertically is not exactly uniform in thickness because of its weight, but wedge-shaped in cross section. When the film is illuminated with violet light of wavelength 405 nm, one sees that a distance of 2.20 cm separates two bright fringes that are 4 orders apart. By how much does the film differ in thickness over this distance?

A thin film of soap solution (n = 1.33) has air on either side
and is illuminated normally with white light. Interference minima
are visible in the reflected light only at wavelengths of 480, 520,
and 1040 nm in air.
What is the minimum thickness of the film?

A soap film (n=1.33) is 772 nm thick. White light strikes the
film at normal incidence. What visible wavelengths will be
constructively reflected if the film is surrounded by air on both
sides? If there is more than one answer, separate them by a
comma.

A soap film in a wire lop is held vertical and viewed under
sunlight. The top part of the film appears black. With the aid of a
diagram, explain, in details, why.

A thin film of soap with n = 1.35 hanging in the air reflects
dominantly red light with ? = 620 nm. What is the minimum thickness
of the film?
Now this film is on a sheet of glass, with n = 1.46. What is the
wavelength of the light in air that will now be predominantly
reflected?

If 47.0 cm of copper wire (diameter = 1.00 mm) is formed into a
circular loop and placed perpendicular to a uniform magnetic field
that is increasing at a constant rate of 10.5mT/s, at what rate is
thermal energy generated in the loop?

A length of 20-gauge copper wire (of diameter 0.8118 mm) is
formed into a circular loop with a radius of 24.0 cm. A magnetic
field perpendicular to the plane of the loop increases from zero to
18.0 mT in 0.20 s. Find the average electrical power dissipated in
the process.
Conducting Loop and Current-Carrying Wire
An infinite straight wire carries current I1 = 5.8 A in the positive y-direction as shown. At time t = 0, a conducting wire, aligned with the y-direction is located a distance d = 51 cm from the y-axis and moves with velocity v = 19 cm/s in the negative x-direction as shown. The wire has length W = 24 cm.1) What is ε(0), the emf induced in the moving wire at t = 0? Define the emf to be...

A circular loop of radius 1.79 m is mounted on top of a truck.
Initially the truck is at rest oriented so that a vector normal to
the loop points north. At this location, the Earth’s magnetic field
has a magnitude of 49.6 μT and a direction of due north, 63° below
the horizontal.
Over the course of 9.0 seconds, the truck accelerates north, so
that at the end of the time interval, the truck is moving at 14.0
