Abichromatic source produces light having wavelengths in vacuum of 450 nm and 650 nm. the indices of refraction are 1.440 and 1.420, respectively. in one situation, a ray of the bichromatic light, in the oll, is incident on the oll-air interface, at an angle of incidence of 40.0 degrees. the angle of dispersion between the two refracted rays in air is closest to to which measure? 2.5° 1.6° 2.8° 1.9° 2.20°

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2

The ph is the a.independent variable b.the dependent variable c.control group
