If a light source is approaching you at a speed very close to the speed of light it will appear to be what color?
That all depends what color it was when it left the source. Whatever wavelength it had at the source, if it's approaching you, you'll measure a shorter wavelength (higher frequency) as it passes you. But don't forget that regardless of the speed or direction of the source, you'll measure the light passing you at the 'speed of light' ... no more or less.
If a light source is approaching you at a speed very close to the speed of light it will appear?
All of the frequencies emitted by the source would appear higher to me, all of the wavelengths would appear shorter, and anything that was visible to me would appear shifted toward the blue end of the spectrum, compared to what it was when it left the source. If, as you say, the source is approaching me at nearly the speed of light, then the 'shift' will be extreme. What left the source as radio waves might be visible to me, and what left the source as visible light might appear to me as hard X-rays or even gamma rays. By the way ... one thing that must be mentioned and appreciated is the fact that even if the source is approaching me at nearly the speed of light, if I measure the speed of the radiation from it as it sails past me, I'll see the radio, visible, X-ray, whatever ... moving past me at the speed of light ... 300,000 kilometers per second. Doesn't matter if the source is moving toward me, away from me, slow, fast, or sideways.
Which of these best described a flight that is approaching the speed of light?
I honestly don't see anything in that list of choices that comes anywhere close to an adequate description.
What distance is the light brightest dimmest?
The closer a light source is to your eye, the brighter it appears - intensity included. The closer you are to the source, the larger the angle of the cone; your pupil as the base and the source as the point. The larger the angle from the point, the more light entering your eye. Too close to the source and your retinal area becomes the limiting factor.
Is Auxin is asymmetrically distributed in shoots because the auxin on the side of the plant facing the source of light is destroyed?
No, the auxin produced on the side facing the light source simply moves to the side away from the light. This causes cell elongation on the side opposite the light, making the stem appear to "grow toward the light"

If a source of light is approaching us at 3000 kmsec then all its waves are?
blue shifted by 1%.
How does a shadow appear?
What you need is a light source and an opaque object to block the light.
Why do shadows get bigger when close to a light source?
deohf
What is related to the amount of light seen?
It depends on how close or how far a light source is.
Who discovered that standing in front of a source of light made a shadow?
oh i thought you ment why does a shadow appear when you stand in front of a light source
Why does the shadow change?
Due how close/far are from the light source
Why do we have shadow?
Shadows are caused when an object is blocking the light causing the shape to appear on the ground in the opposite direction of the source of the light. A shadow only appears in the light or when any shining object faces them. All objects in the way of the light will appear with a shadow in the opposite direction of the source of the light.
Can a shadow appear larger depending on the size of the light source?
Yes, yes it can!
How can you get blinded by light?
Stand with your back to a very bright light source and close your eyes tightly.
What is the source of radiation of a dissecting microscope?
The source of radiation of a dissecting microscope is light. The illuminated light is what will cause the image to appear in three-dimensional format.?æ
