Physical Science B(Wed.)

No Bellwork Today

Please take out your laptops.  Open up examview.  Log in and be ready for the password.

Please finish the home energy audit.  Turn it in after the test.  You should have filled in the spreadsheet and answered the discussion questions prior to today.

Physics B(Wed.)

Bellwork:
    1.  Explain how a wavelength can be defined on a longitudinal wave.

    2.  Explain why a mechanical wave travels faster in a solid than in a gas.

Today, we will discuss sound and its characteristics.

Explain the doppler effect and the formula that goes along with it.

IF you did not finish the reflection lab, please do so now.  If you need to set up the target, please get that ready and I will test it for you.

HW:  Doppler effect problems. 

We will have a quiz over wave characteristics and sound on Friday.  Be sure to study.
