Yield Stress and Normal StressOutline Current Lecture 1) Continuation of waves2) Drawings of waves to offer a better explanationCurrent Lecture- For earthquakes within 100km- sheer waves are more disastrous, more energy polarization: wave splits into 2 waves traveling in the same directionThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- elasticity drives waves! - love waves? Show waves trapped in the crust by total internal reflection - nuclear test ban treaty: explosions tend to be mostly P waves - earthquakes are much most rich in sheer waves- Waves= when going slow, material into fast, waves (or toy car) will refract so they are traveling more parallel to the interface in the fast material. - Surface waves: Rayleigh waves ◦ love waves- At some critical angle of incidence, (ic) waves will refract parallel to the interface.These waves are now trapped in the slow
