Re-test Light, Lenses and Mirrors) 1) What is reflection? 2) What type of image is produced by a plane mirror and how do we know it\'s that type? 3) Draw a ray diagram for the mirror shown below. 4) What is Snell\'s Law and what is it used for? 5) Why is a concave lens considered to be diverging? When light strikes the boundary coming out of a dense medium, such as glass, heading into air, it bends, but only if it hits at an angle; which direction does it bend? 6) 7) Why doesn\'t light bend or refract if it hits a surface at a 90 angle? What type of image is produced by a convex lens when the object being viewed is placed farther away than the focal point, and how can we see it? 8) diffracted waves cross paths and overlap to produce fringes. What are they and why are they created? 9) When a wave is made to pass around more than one boundary or obstacle the 10) Why does dispersion occur for white light?
Solution
1) Reflection refers to the change in direction of the light ray back to the medium it came from at an interface between two different media.
Can answer only one question according to chegg policy. Thank you for understanding. Hope it helps :-)
