1
Q
what’s the equation linking orbit speed, 2 x pie x orbit radius and Time Period
A
orbit speed = 2 x pie x orbit radius / time period
2
Q
what is the Doppler effect
A
(h-ho)/ho = (Deltah/ho) = v/c
3
Q
what does ho mean
A
apparent wavelength
4
Q
what does h mean
A
actual wavelength
5
Q
what does (h/ho) = deltah mean
A
(h/ho) = deltah = change in wavelength
6
Q
what does v mean
A
v = speed of object
7
Q
what does c mean
A
c = speed of light
