The index of refraction of silicate flint glass for red light is 1.620 and for violet light is 1.660. A beam of white light in this glass strikes the glass-air interface at a 29.10° angle of incidence and refracts out into air. What is the angular separation between the red and violet components of the spectrum that emerges from the glass?
Two diffraction patterns are formed on the screen. What is the distance between the common center of the diffraction patterns and the first occurrence of the spot where the dark fringe from one pattern falls on top of a dark fringe from the other p..
We know that a spherical charged particle of will have an external electric field of E = k q/r2, where k = 8.988×109N·m2·C-2 is the Coulomb constant, q is the charge, and r is the distance from the center of the spherical particle.
An osprey's call is a distinct whistle at 2200 Hz. An osprey calls whereas diving at you, to drive you away from her nest. You hear call at 2220 Hz. How fast is the osprey approaching.
A car travelling at 25.0 m/s runs out of gas while travelling up a 33.0 degree slope. How far up the hill would it coast before starting to roll back down.
A 10kg mass that is moving at 15m/s hits a stationary 10kg mass. The collision is elastic. what is the total momentum BEFORE the collision
Calculate the speed of a proton with a kinetic energy of 1.48 eV, Find the speed of an electron that has a kinetic energy of 1.48 eV. 1 eV = 1.602 × 10^?19 J
What are the size and direction of the change in velocity if the initial velocity is 6 m/s south and the final velocity is 2 m/s west?
What the stopping distance of the car is as measured from the point where the driver first notices the red light.
suppose that r2/r1 = 10.0 cm and ignoring any air inside the shell, find the temperature of the outer surface of the shell.
An unstrained horizontal spring has a length of 0.37 m and a spring constant of 340 N/m. Two small charged objects are attached to this spring, one at each end. The charges on the objects have equal magnitudes.
A 0.20 kg block on a vertical spring with a spring constant of 5 multiplied by 103 N/m is pushed downward, compressing the spring 0.090 m. When free, the block leaves the spring and travels upward vertically. How high does it rise above point of r..
The car has just achieved double its initial velocity when the driver spots a police officer behind him and applies the brakes. The car then slows down, coming to rest at the stoplight ahead.
