Red shift is of virtually no importance in determining the age of stars within our galaxy or local group. But the red shift is crucial for measuring relative velocities of those stars with respect to us. Stars approaching us are blue shifted, such as the stars in the Andromeda Galaxy. We can also determine which direction the galaxy is spinning, as the light of stars one one side will be shifted less than the light of the stars in front, or on the other side.
Starlight from galaxies well beyond our local group are uniformly shifted towards the infrared end of the visible spectrum, varying with the distance of those galaxies from us. The further away they are, the deeper red the light is from them, indicating the greater their recessional velocity.
I cannot think how stellar age might correlate with red shift.
When light shifts toward the blue end of the spectrum, it is shifting in the direction of shorter wavelengths. This happens when a luminous object, such as a star, is moving toward you. This motion tends to compress the waves which it emits. Stars that are moving away from the observer will instead exhibit a red shift. The waves are stretching out, because of the motion. And because the universe is expanding, red shifts are by far the most common.

A lateral (sideways) movement doesn't change the frequency, because in this case, the distance between the object and the observer isn't changing.
Blue shift as you get closer because by the Doppler effect, the frequency of the light increases, so the light seems more blue. Using the same logic, there is a red shift for light as you move away from stars.
One of the most reliable methods employed presently is using Hubbles Laws and Constant, utilizing the red shift. RED SHIFT A+LS (:
Motion parallax.
The frequency determining components in a phase shift oscillator are the series of resistive/capacitive filters on the output of the inverting amplifier. See accompanying link.

This can be answered using light or sound. Light will remain at a constant speed regardless of frequency or amplitude. Its shift in frequency (Doppler shift) is caused by the extreme distances the light had to travel to get here. Still it remains at the same speed. Sounds speed will change with local conditions. Also subject to an audible Doppler shift when a constant note is moved past you you can hear the pitch shift. The motion compresses the sound as it approaches and spreads it out as it moves away from you.

how do you replace shift indicator light escalade 2003
The 2000 BMW shift light is computer programed to go on and off at the appropriate times. You can remove the shift light fuse to keep the light off permanently.
Never heard of a speed light. The only thing I can think of that you might be talking about is a shift light. This light is used to indicate shift points. Shift when the light comes on. All of the lights on you dash are explained in your owner's manual.
The green 'D' light on the dash panel might flash on a CRV 2002 Sport when it is in motion, because it is telling the driver that the transmission needs to shift to a higher gear. If the vehicle is equipped with Overdrive, this gear should be used unless towing a trailer. If the vehicle has a manual transmission, it is telling the driver to shift to a higher gear.
You will use more gas due to the higher RPM. The shift light is to help you to save on gas milage.
