Best with a smooth surface If not for this behavior of light, your mirror
would not work!
Light wave changes speed
Most microscopes and some telescopes
use lenses that take advantage of this
behavior of light
This occurs when light bounces off of a
surface
This behavior of light allows the lenses in
your glasses to bend incoming light waves
This occurs when light moves from
medium to another, like water to air
Reflection
Refraction

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
