Is a behavior in which animals move toward or away from a light source?

It depends on if a animal is nocturnal or not. nocturnal animals move away from light usually because there mostly used to the dark....you be welcome.

Why is a shadow always on the opposite side of the light source?
Your shadow will fall in the direction opposite the source of light - with you between the light source and the shadow. The direction of your shadow relative to you will depend on what direction you are facing.If you are facing toward the light source, the shadow will be behind you.If you are facing away from the light source, it will be in front of you.If you have the light source to your right, the shadow will be to your left.If you have the light source to your left, the shadow will be to your right.If the light source is directly above you, the shadow will be directly under you.If you move past a light source, your shadow will move from behind you to beside you and then to in front of you.
What phenomenon is the basis of police radar and makes light or sound waves increase in frequency if the source is moving toward the observer and decrease if the source is moving away?
Its called the doppler effect.
If light experiences the Doppler effect what will happen to its color?
If light is subject to the Doppler effect, it will change color. The light changes color toward the lower (red) end of the spectrum or the upper (blue) end of the spectrum. Which way the color shifts depends on whether the distance between the source and the observer is increasing or decreasing. Should we find the distance is increasing, the light will be shifted toward the red end of the spectrum. This is called redshift (one word), and astronomers know this well because most all galaxies are speeding away from the Milky Way and have their light shifted toward the red end of the spectrum. If the distance between a source and observer is decreasing, the color of the light will be shifted toward the blue end of the spectrum. In either case, the amount the color is shifted will be determined by the rate the distance between the source and observer is changing. If a galaxy is moving away from the Milky Way, we'll see a shift toward red, and if another galaxy is moving away faster, will see a greater shift in the color of the light from it.
Is a traffic light a light reflector or light source?
light source
Is a flame a source of light?
The flame of a candle is a source of light.
Can plants use light as sun?
Sure. In fact, if you place a plant under an artificial light source, it will lean toward the light source as if it were the sun.
What are some examples of photokinesis?
A plant that responds to light. Typically a plant will position itself toward a light source.
An apparent shift in the wavelength of light emmited by a light source moving toward or away from an observer is known as?
The Doppler Effect.
What part of a plant is most likely to grow toward a light source?
The budding tip where the leaves form.
Why is your shadow sometimes in front of you and sometimes. behind you?
Your shadow will fall in the direction opposite the source of light - with you between the light source and the shadow. The direction of your shadow relative to you will depend on what direction you are facing.If you are facing toward the light source, the shadow will be behind you.If you are facing away from the light source, it will be in front of you.If you have the light source to your right, the shadow will be to your left.If you have the light source to your left, the shadow will be to your right.If the light source is directly above you, the shadow will be directly under you.If you move past a light source, your shadow will move from behind you to beside you and then to in front of you.
Why does light affect plants?
The more light there is, the more energy a plant can make through photosynthesis. That's why plants will always grow toward a light source when planted.

When was Toward the Light created?
Toward the Light was created in 1920.
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"
How do different kinds of materials affect the behavior of light?
Sound and light are both forms of energy that is carried from one place to another.they travel in all directions from the source.
How do light waves appear to an observer as the light source moves towards the observer?
If we measure the spectrum of the light, we can determine whether the light is moving toward us or away from us. Sunlight looks white, but is actually made up of thousands of individual colors, and the amount of each color depends on what the star is made of. In the far future, spacemen will be able to detect which star is which, by measuring the spectrum of the light. By measuring the pattern of the spectrum, and the exact frequency of the light waves, we can determine whether the light source is moving toward us or away from us. (Actually, that isn't exactly true; we couldn't tell if it was moving toward us, or WE were moving toward IT. But we will know what we're getting closer together.) There is one other "Gotcha!" about this. If the spectrum indicates that the light source is moving away from us, it is possible that the light source is very near a black hole. Gravity affects light just like it affects mass, and sometimes it is difficult to tell whether the light source is moving away, or if gravity is pulling the light away. Usually, we will be able to determine which is happening from other measurements.
What is the velocity at which a mooving observer can see the red light as green Doppler?
Observer would have to move toward the light source at about 1/5 the speed of light. A little over 37,000 miles/sec.
