What is the relationship between the Doppler effect and the Hubble red shift?

[Planter]

Homework Statement

The car is approaching a radio station at 25m/s. Broadcast frequency is 74.5 MHz.

What change in frequency does the driver observe.

Homework Equations

Doppler effect on EM waves

Fo = Fs (1 (+/-) u/c)

u = speed of observer

c = speed of light

The Attempt at a Solution

Got it ,, answer is 62.08 Hz

Homework Equations

I really don't know. The answers should be between chapters 26-29 of the Serway book.

But I am drawing a blank. "clearly not the doppler effect" right?

The Attempt at a Solution

Reading doppler effect right now.

Definitely the Doppler Effect. Keep on reading a bit, and you'll see it addressed. Show us what you get for an answer!

Are you sure? Because doppler effect was taught "last semester" in part one of this class. Which is why I am weary of using it... It's not sound frequency i don't think.

Well, what is the Doppler Effect (define it in your own words -- don't look up the definition yet)?

And, what would be different if the source was a stationary whistle, instead of a radio station? What would be the same?

The frequency is in MHz.. Would a doppler effect question be in MHz??

Ok, I got it.. Found it,, haha Doppler effect on EM waves, Chapter 21.13... Thank god for PDF books. I was only searching in chapters 26+ because all the questions prior to this one was pertaining.

Just to complete this learning module, please do a quick search on the Hubble Red Shift (at wikipedia or elsewhere). Do you see the theme?
