A layer of oil of thickness 200nm floats on top of a layer of water of thickness 400nm resting on a flat metallic mirror. The index of refraction of oil is 1.24 and that of the water is 1.33. A beam of light is normally incident on these layers. What must be the wavelength of the beam if the light reflected by the top surface of oil is to interfere destructively with the light reflected by the mirror?

A 10.0-uF capacitor, a 40.0-uF capacitor, and a 100.0-uF capacitor are connected in parallel across a 12.0v battery. what is the equivalent capacitance of the combination
In traveling to the Moon, astronauts aboard the Apllospacecraft put themselves into a slow rotation to dsitribute theSun’s energy evenly. At the start of their trip, theyaccelerated from no rotation to 1 revolution per minute during a12- min time ..
A certain superconducting magnet in the form of a solenoid of length 0.70 m can generate a magnetic field of 10.0 T in its core when its coils carry a current of 50 A. The windings, made of a niobium-titanium alloy, must be cooled to 4.2 K. Find the ..
A 1.40 kg iron horseshoe is taken from a forge at 950°C and dropped into 4.00 kg of water at 14.0°C. Assuming that no energy is lost by heat to the surroundings, determine the total entropy change of the horseshoe-plus-water system.
A hypodermic syringe contains a medicine with the density of water. The barrel of the syringe has a cross-sectional area A = 2.60 10-5 m2, and the needle has a cross-sectional area a = 1.00 10-8 m2. In the absence of a force on the plunger, the pr..
