What else can I help you with?
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?
To find the illuminance at a certain distance from a light source, you can use the formula: illuminance = luminous flux / (4 * π * distance^2). Plugging in the values gives: illuminance = 1275 lm / (4 * π * (5 m)^2) ≈ 6.43 lux.
What happens to the shadow as this light source moves?
As you move farther away your shadow get bigger and goes away
What happens to your shadow when you move away from light?
Your shadow will become longer and less defined as you move away from the light source. If you move further away, your shadow may eventually disappear completely depending on the distance from the light source.
What happens to light as it moves away from its source?
As light moves away from its source, it spreads out and becomes less intense. This is known as light attenuation. The further the light travels, the more it scatters and loses energy, resulting in a decrease in brightness.
What happens when a light moves away from Earth?
As a light source moves away from Earth, its light waves become stretched out, causing a shift towards longer wavelengths known as redshift. This is due to the Doppler effect, where the frequency of light is altered by the motion of the source relative to the observer. This redshift can indicate that the object emitting the light is moving away from us.
What happens if a source of light is moved away from the focus of a parabolic reflector?
The light will start to diverge instead of being focused at a single point. The farther the light source is moved from the focus, the more the light will spread out and the less focused it will become.
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
What happens to the fuzzy region around the edge of the central region when the light source is moved away?
When the light source is moved farther away, the fuzzy region around the edge of the central region will decrease in size. This is because the light rays spread out less as they travel a greater distance, resulting in a sharper shadow edge.
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.
What will happen to the size of the shadow if the object moves away from a tilted source of light?
If the object moves away from a tilted source of light, the size of the shadow will decrease. This is because as the object moves away from the light source, the angle at which the light hits the object decreases, resulting in a smaller shadow being cast.
When light shines on an object the side away from the source of light looks?
darker from lack of exposure to the light.
