3/14

Objective:  SWBAT experimentally determine the index of refraction of a piece of glass.


Warm Up:  Pick up one copy of the lab and preread the instructions.

3/13

Objective:  SWBAT use Snell's Law to calculate the refraction of a light ray.


Warm Up:  Get out your calculator, pencil and pick up a ruler.  Quiz Time.

3/12

Objective:  SWBAT calculate the magnification of a curved mirror.


Warm Up:  An object is places 12 cm in front of a mirror whose magnification is -5.   What is the focal length of the mirror?

3/9

Objective:  SWBAT calculate the image location and height in a mirror.


Warm Up:  An object is placed 10 cm in front of a concave mirror whose focal length is 8 cm.  Using a ray diagram, determine where the image will form, and its type ,size and orientation.

3/7

Objective:  SWBAT explain how electromagnetic waves propogate and list the types of EM waves.


Warm Up:  Draw a diagram of the EM spectrum and label the 7 types of EM waves.

3/5

Objective:  SWBAT review to tomorrow's test on characteristics of waves and sound.


Warm Up:  A car moving 20 m/s away from you sounds it horn whose true frequency is 950 Hz.  What frequency do you hear?

3/2

Yesterday's Lab will be due next Wed.


Objective:  SWBAT calculate the harmonic frequencies of a wave.


Warm Up:  When all the keys on a flute are depressed the lowest note that it can play is middle C.  If the speed of sound in air is 343 m/s and assuming the flute is a cylindrical tube open at both ends, determine the length of the flue from the mouthpiece to the end of the tube.
