Which statement explains how constructive interference supports the wave model of light rather than the particle model?
A. Light strikes a metal surface and knocks electrons loose, which
particles would not do.
B. Two light beams intersect, joining together to form a brighter
beam, which is a behavior of waves.
C. Light waves bend around a corner, but particles would not travel in
bent paths.
D. Two beams of light intersect, canceling each other out and
forming a weaker beam, which is a behavior of waves.

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
