4/11/19 EXAM 3 Problem 1. Circuits. (a) Consider the circuit in the diagram. Us- ing Kirchoff's Laws, 'solve' the circuit, including finding all the currents and volt- age drops. In particular, you should fig- ure out what value of R will result in 10 a b points a and b having equal electric po- tential. (In other words, the potential difference a.k.a. voltage between a and b is zero.) 20 L (b) Supposing that part (a) worked, and points a and b have equal electric potential, what would happen if they were connected by a wire? How would the circuit change, if at all? (c) Suppose that the circuit was further modified by replacing the resistor R with an uncharged capacitor C. Assume the wire from part (b) IS present. Describe, in as much detail as you can (words and equations are both good), what will happen to the circuit over time. If you can, compute the final voltage across the capactor (after many many time constants have passed).
Refraction of Light
Refraction is a change in the direction of light rays when they travel from one medium to another. It is the bending of light when it goes through different media.
Angle of Refraction
Light is considered by many scientists to have dual nature, both particle nature and wave nature. First, Particle nature is one in which we consider a stream of packets of energy called photons. Second, Wave nature is considering light as electromagnetic radiation whereas part of it is perceived by humans. Visible spectrum defined by humans lies in a range of 400 to 700 nm wavelengths.
Index of Refraction of Diamond
Diamond, the world’s hardest naturally occurring material and mineral known, is a solid form of the element carbon. The atoms are arranged in a crystal structure called diamond cubic. They exist in a huge variety of colours. Also, they are one of the best conductors of heat and have a very high melting point.
