Select all the true statements about this situation. (select all that apply.) for completely destructive interference to occur at the orange point, the path-length difference for the orange point must be an integer number of wavelengths plus half a wavelength. the path-length difference is the distance the point is from the left source minus the distance the point is from the right source in this particular case, the orange point is 1.5 wavelengths farther from the left source than it is from the right source when we say that completely destructive interference occurs at the orange point, the net displacement must be zero at all times at that point. for completely destructive interference to occur at the orange point, the distance from each source to the orange point must be an integer number of wavelengths plus half a wavelength. (b) in this case, what is the distance between the two sources, in terms of wavelengths? x wavelengths (c) let's say that the wavelength in this case is 20.0 cm, and the distance from the source on the right to the orange point is 70.0 cm. what is the distance from the source on the left to the orange point? cm

Aparticle of mass m is projected with an initial velocity v0 in a direction making an angle α with the horizontal level ground as shown in the figure. the motion of the particle occurs under a uniform gravitational field g pointing downward. (a) write down the lagrangian of the system by using the cartesian coordinates (x, y). (b) is there any cyclic coordinate(s). if so, interpret it (them) physically. (c) find the euler-lagrange equations. find at least one constant of motion. (d) solve the differential equation in part (c) and obtain x and y coordinates of the projectile as a function of time. (e) construct the hamiltonian of the system, h, and write down the hamilton’s equations (canonical equations) of motion.

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90
