When sound passes from one medium to another where its propagation speed is different, does its frequency or wavelength change? Explain your answer briefly.
Day 23 2/29/2016 Physics 5b Homework 8 is up on geometric objects reflection and refraction This week we will use lenses before we understand them Friday we will hold an additional lecture: 5:106:30pm in the Earth & Marine Classroom the lecture will be recorded Sunlight as it passes through the atmosphere is polarized: the wave travels in the direction perpendicular to the electric field there is no energy transported in the direction of the electric field If the wave strikes an atom: the energy by the wave that is generated cannot travel in the direction of the electric field but in the perpendicular direction we can measure the wave as a source If we measure a beam, we will see a wave that is polarized like the incoming wave Incoming wave that strikes a surface: we have the reflection plane, and the incidence place and we want to figure out how polarization occurs in this case: we will refer to the angles of incidence angle of incidence = angle of refraction We will see some intensity / radiation
