Question 2: Morse Code (15) Morse code has been one of the most basic communication protocols and still used today to convey SOS messages and other urgent communications. In Morse code, each English alphabet is encoded by a sequence of '.' and '-', see Figure 1 for complete mapping between English alphabets and Morse codes. Letters are separated by spaces and words by "/". Your task is to design a program that can 1. convert any given string into a Morse code sequence char* ConvertToMorseCode (char*) and 2. a Morse code sequence to a string. char* convertToString(char*) You are not authorized to use string data type, however you can use char*.

Closed Book (Equation Sheet is Attached) 1. (20%) 6 An energy versus momentum (E vs. k) diagram for PbSe is shown to the right. Note that the Fermi energy is located above the bottom of the conduction band. a) What can you say about the electron concentration in this material? The majority of the electrons will be in the bottom of the conduction band. Though, with enougth energy some could be in the Valerice band as well. b) What can you say about the hole concentration in this material? The majority of the holes will be in the upper part of the Valence ba c) Suppose the Fermi energy is 20 meV above the bottom of the conduction band. What is the lowest energy photon that can be absorbed by this material if it is at zero Kelvins.
