Aplane wave of monochromatic light is incident normally on a uniformly thin film of oil that covers a glass plate. the wavelength of the source can be varied continuously. fully destructive interference of the reflected light is observed for wavelengths of 517 and 632 nm and for no wavelengths in between. if the index of refraction of the oil is 1.33 and that of the glass is 1.50, find the thickness of the oil film.

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
