Hope You’re Having a Great Summer!!!

This is soooooo cool! Wow, sounds like a great summer project! (Get it? Sounds? :)) Or maybe a project for my budding physics students? Hope you are having a great summer break!!

Psalm 19: 1 -3, “The heavens declare the glory of God; and the firmament shows His handiwork. Day unto day utters speech, and night unto night reveals knowledge. There is no speech nor language where their voice is not heard.”

Physics 4-12-18 Characteristics of Light & Plane Mirrors

PHYSICS: So much fun with light! Here’s the lecture on the characteristics of light, polarization, reflection and plane mirrors. We’ll play with mirrors and the reflection of light a bit more tomorrow!

Physics 4-5-18 Harmonics & Beats

PHYSICS: So why do instruments that are playing the same note sound so different? Here’s our discussion of harmonics and beats.

Speaking of discussion – what did you think about the Tacoma Narrows Bridge? Any ideas on an explanation? Here’s a link, if you’d like to see it again: Tacoma Narrows Bridge

Lab update – Friday’s lab has been changed to the thLAB: Waves and Interference.

Physics 4-4-18 Sound Intensity and Resonance

PHYSICS: Great discussion of intensity and resonance today! Were you okay with the problems?

Couple of items to apply for further contemplation – so how does the whole hearing thing work? I mean, I know the little bones in your ear move, but why? Is resonance involved? Great item for application/discussion! And here’s another – so how in the world did that crystal glass shatter?

Physics 3-28-18 Waves

PHYSICS: Hey guys! Here’s our discussion on the properties of waves. Remember anything from your earlier 8th grade physical science days? Problems are pretty simple for you, I think. Do you remember the main formula from chemistry? Speed = wavelength x frequency (c = λf).

HOMEWORK UPDATE: All the book homework from waves will be due Friday.

Easy peasy – and don’t forget the applications!
