When a source of light approaches an observer the light appears to be than it actually is?
Blue shifted and when it is moving away it is under a red shift.
How do you make a smaller and clearer shadow when you can not move the object?
Move the light source farther away from the object.
How are light rays coming from a point source of light different then larger source?
From a point source, the light spreads out in all directions and adjacent light waves diverge from one another. From a larger source, it appears more like the light waves are moving parallel to each other, with little divergence. It's a relative thing. From the perspective of Earth, the Sun's rays are all parallel to each other because the Sun is huge and also because we are so far away from it. So the key differences are: 1. Small, point like source. 2. Being close to the source. Combinations of 1 and 2 above produce more divergent rays. Either of 1 and 2 below (or a combination of the two) will produce more parallel rays that don't diverge much. 1. Large light source 2. You're far away from the source.
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.
How many light years away is your sun?
The sun is not light years away but light minutes and the sun is 8 (rounded) light minutes away from us. But if you really want to know how far away the sun is from us in light years it is 0.000015 of a light year away from us.
What is the illuminance on a table that is 5 m away from a source of light that has a luminous flux of 1275 lm?
51 lux
What happens to light as it moves away from its source?
It dims......Nikki
What happens to the shadow as this light source moves?
As you move farther away your shadow get bigger and goes away
What happens if a source of light is moved away from the focus of a parabolic reflector?
Then the focused beam is no longer parallel, and is spreads faster from the axis as it proceeds away from the reflector.
When the base of the stem is covered with an opaque shield the stem bends away from the light source true or false?
False because nothing happens
How far away is light from us in km?
It depends where the light source is.
Is the speed of light faster further away from its source or closer?
The speed of light is constant, regardless of how far it is from its source.
When light shines on an object the side away from the source of light looks?
darker from lack of exposure to the light.
What does it mean if a star is experiencing a red shift?
redshift is what happens when visible light gets longer in wavelength, thus shifting toward the red end of the spectrum of visible light. This is a phenomenon that occurs when the light source is moving away from the observer.
How does light rays move away from their source?
The light gets dimmer and eventually will die out.... it will only die out if the source stops giving off light. The answer man
Why when the length and position of my shadow changes as i walk towards a light source and when i walk away from the lamp post?
If the direction from which the light comes changes, then the direction of the shadow changes as well. The shadow basically points away from the light source.
What are light waves that moves together as they travel away from their source?
coherent
