A plane polarized electrodynamics wave travelling in a dielectric medium of refractive index 'n' is reflected at normal incidence from the surface of a conductor.find the phase change undergone by its electric vector if the refractive index of the conductor is n2=n(1+ip)
Let us use the uncertainty principle to (very roughly) estimate the size of a hydro- gen atom. Picture the hydrogen atom as an electron orbiting a proton at close to the speed of light.
A double slit experiment is performed with 589 nm light and slits-to-screen distance of 2.00 nm. The tenth interference minimum is observed 7.26 mm from the central maximum. Determine the spacing of the slits.
A 50.7-kg crate rests on a level floor at a shipping dock. The coefficients of static and kinetic friction are 0.628 and 0.358, respectively. What horizontal pushing force is needed to (a) just start the crate moving and (b) slide the crate across th..
a spring is hanging down from the ceiling and an object of mass m is attached to the free end. the object is pulled
a child pulls a 3.00-kg sled across level ground at constant velocity with a light rope that makes an angle 34.0deg
A metal plate of area 0.05 m^2 is connected to an eight-gram mass via a string that passes over a pulley. A lubricant with a thickness 0.3mm is placed between the plates and the surface. When released the plane observed to move to the right with a..
A dielectric of k=3 is inserted between two charged parallel plates, completely filling the 2cm space between them. what is the new voltage across the plates
The triangular coil of wire in the drawing is free to rotate about an axis that is attached along side AC. What is the magnetic moment of the loop
oppositely charged parallel plates are separated by 5.38 mm. a potential difference of 600 v exists between the
A sinusoidal electromagnetic wave from a radio station passes perpendicularly through an open window that has area of 0.600m^2. How much energy does this wave carry through the window
A particle undergoes three successive displacements in a plane, as follows: 3.50 m southwest, 4.50 m east, and 6.00 m in a direction 60.0° north of east. How do you find the components of the first displacement
A leaping frog leaves the ground with a speed of 4 m/s heading straight upward. The frog's mass is 100 g (so its weight is 1 N). What is the maximum height reached by the frog through this leap? Look back at the formulas for gravitational potential e..
