A Quiet Monday

What can one say about a day like Friday? Pretty much everyone had a horror story about power outages, property damage or overall chaos to describe. Thankfully, folks are in the process of getting back to normal and we got an unexpected 3-day weekend as a bonus.

Honors Physics finished up their sound material with a discussion of beats. Alternating areas on constructive and destructive interference produced by waves of different frequencies arriving at the ear at the same time. By counting the beat frequency, one can determine how many hertz the notes are apart. Time was given in class to work on the mixed review sheet for the chapter in preparation for tomorrow’s exam review. Bring all questions with you tomorrow as we prepare for Wednesday’s sound exam.

Physical Science B watched a video on color and light that nicely summarized the light topics to date. Tomorrow, we’ll go over the homework for reflection and color and then turn out attention to refraction and diffraction.

Physical Science E conducted their lab investigation on light reflectivity, polarization and intensity. As for B Block, the data demonstrated that color and texture have an effect on reflectivity, polarizing filters show maximum reduction in light intensity when oriented at 90 degrees to each other and light intensity decreases with distance with an inverse-square relationship. Tomorrow, we discuss the lab and then move on to refraction and diffraction.

Physics F and G reviewed harmonics and beats and then worked on review material for the chapter. Tomorrow – full period exam review. Wednesday – exam. Thursday – moving on to light and reflection.
