一、考纲要求参照高中物理选修3-4考试说明。二、高考考查题型、考查重点、难易程度、所占分值考查题型:一个6分的选择题和一个9分的计算题。考查重点:(1)机械振动与机械波(2)折射率和全反射。难易程度:选择题比较简单,计算题考查计算能力和基础知识掌握,也较简单。考查知识点:折射率的计算、全反射条件、波长波速频率三者关系、干涉加强点(减弱点)的条件、机械振动与机械波传播、振动图像与波动图
First, the syllabus requirements reference high school physics elective 3-4 exam description. Second, the college entrance examination exam questions, test focus, degree of difficulty, the share of test questions: a 6-point multiple-choice questions and a 9-point calculation questions. Examination focus: (1) mechanical vibration and mechanical wave (2) refractive index and total reflection. Degree of difficulty: multiple-choice questions are relatively simple, calculation of exam calculation ability and basic knowledge mastery, but also simpler. Examining the knowledge points: the calculation of refractive index, total reflection conditions, the relationship between the wavelength of the wave speed and frequency, the point of weakening (interference point), mechanical vibration and mechanical wave propagation, vibration image and fluctuation
