A thin film of glass (n = 1.50) floats on a liquid of n = 1.35and is illuminated by light of a wavelength = 580nm incidentfrom air above it. Find the minimum thickness of the glass, otherthan zero, that will produce destructive interference in thereflected light.
A luggage handler pulls a 20.0-kg suitcase up a ramp inclined at 24.0° above the horizontal by a force of magnitude 148 N that acts parallel to the ramp. Calculate the work done on the suitcase by the force
