Homework E block

Investigate and write meaningful definitions for these concepts -

Index of refraction

Snell's law

homework (C)

Find the meaning/definition of the following:

Snell's law

Index of refraction

Also, examine your data/graphs - particularly the graph of sin (theta 2) vs. sin (theta 1). Does it make sense in light of Snell's law?

homework

C block - none! (You just finished the test.)

E block - study for test.

Electromagnetic Spectrum

Recall that waves can be categorized into two major divisions:

Mechanical waves, which require a medium. These include sound, water and waves on a (guitar, etc.) string

Electromagnetic waves, which travel best where there is NO medium (vacuum), though they can typically travel through a medium as well. All electromagnetic waves can be represented on a chart, usually going from low frequency (radio waves) to high frequency (gamma rays). This translates to: long wavelength to short wavelength.

All of these EM waves travel at the same speed in a vacuum: the speed of light (c). Thus, the standard wave velocity equation becomes:

c = f l

where c is the speed of light (3 x 10^8 m/s), f is frequency (in Hz) and l (which should be lambda) is wavelength (in m).

HW

For C block - Go through your notes and generate a review page.

For E block - that will be your homework after Thursday's class. For tomorrow, make sure you did the Doppler problem creation already assigned.

Thanks!

Hw

Oops

I posted the homework (for E block) on the wrong blog - homework is to create and solve your own Doppler effect problem, with at least 4 parts.

This is the same hw as is due Wednesday for C block.

Thanks!
