NAME: KABUGI PAUL MURIGUADMISSION NUMBER:ENH/2019/47045BPY 2110 MODERN PHYSICS ASSIGNMENT 1LECTURER: MR. NDIRITU MOSESDEADLINE: JUL 7, 2021 9:35 AMINSTRUCTIONThe highest level of learning in the Bloom's Taxonomy is the CREATE level. At this level, a learneris supposed to Design, assemble, construct, Develop among other. Therefore, from the course outline,DESIGN five (5) questions worth 20 marks each of not more than 5marks subsections (total100marks) from anyFiveareas in the course outline. For each question set, provide a marking guide(Answers). Marks will be awarded as per the quality of questions and accuracy of answers.PHYSICAL CONSTANTSPlanck constant; h = 6.626x10-34JsCharge of proton; e = +1.602x10-19CMass of electron; me= 9.109x10-31kgAcceleration due to gravity, g = 9.81 m s-2Avogadro constant; NA=6.023x1023mol-1Rydberg constant; Rhc= 1.097x107m-1Speed of light in vacuum; c = 2.998x108ms-1Charge of electron; e = -1.602x10-19CMass of proton; mp= 1.67 x10-27kgRest energy of electron; Ee= 0.511MeVOne atomic mass unit; u= 1.66x10-27kgAtomic mass unit energy equivalent; a.m.u = 931.5MeVOne ElectronVolt; 1eV = 1.602 x 10-19JQUESTION 1(i)Explain the de Broglie theory. (3mks)
(ii)What is half-life in radioactivity? (2mks)
(iii)Explain ANY three uses of X-rays (3mks)
2.Diagnosing InjuriesA bone x-ray will use a small amount of ionizing radiation. It will produce pictures of a bonein the body. This will help doctors diagnose joint dislocation or fractured bones. This x-rayallows the doctor to assess bone fractures or injuries. This exam isn t hard to prepare.3.Dental Check
