How does a shadow change when the light source is moved?
Depends where the light source is located and how many. Light will diffract around objects, so depending on the size of the object and the distance the light source is from it, more than one shadow can be cast, or at least it can have larger or smaller blurry edges which change when the light source is moved.
Why does your body create a shadow?
Any opaque object which obstructs the path of light will create a shadow. For that very reason, our body, being opaque, creates a shadow when cast in front of a light source, such as, the sun.
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.
Why are all shadows black?
Because a shadow is where light does not reach, and black is the absence of light. Where there is more than one light source, a shadow may occasionally appear a different colour.
What light does a very hot light bulb produces more of what type of light than a light that is cool to the touch?
yes
When will an object cast 2 shadows?
Yes, it can. A shadow is caused by the interruption of light from a single source. If you have more than one light source, you can have more than one shadow. Some shadows may not be as distinct (diffused light, shadow on brightly lit surfaces, etc.), and multiple shadows will practically always overlap to some extent.
Which of the areas of technology best classifies the light bulb?
The incandescant light is more of a heat bulb than a light bulb, being 200% less efficient (on average) in producing the same amount of light (measured in lumens) than a fluorescent bulb. That being said, the light bulb would be considered part of a luminaire.
Does an object in a path of light waves cast a shadow?
Yes it does.
What is a word that means a light bulb that uses more energy than a fluorescent light bulb?
incandescent
What is the difference between a shadow of an object created by a small light source and the sun?
Shadow from light source always bigger than object but shadow from the sun is the same size as object. Great different is due to the distance of light source. Size of shadow is double at distance x 2 source to object. Shadow is always bigger than object. You will notice your shadow is bigger in light bulb or stadium spot light but the shadow from sun is the same size as object. This is due to great distance from sun to us (150 million km approximately) the double distance to see our shadow to be double is at 300 million km from the Sun. at merely 10 m or 100 km is almost no distinguishable different in shadow size to the object. We then presume shadow cause from sunlight is equal to the size of the object.
How does a shadow change when the light source is moved?
Depends where the light source is located and how many. Light will diffract around objects, so depending on the size of the object and the distance the light source is from it, more than one shadow can be cast, or at least it can have larger or smaller blurry edges which change when the light source is moved.
Does a larger battery contain more energy than a smaller light bulb?
A light bulb contains no energy so, Yes, a battery of any size contains more energy than any light bulb.
Why is the light bulb more important than the Internet?
the light bulb is just important yeah you dumb computer
Does a 25 watt light bulb draw more current than a 60 watt light bulb?
No, a higher wattage INCANDESCENT light bulb uses more current than a lower wattage INCANDESCENT light bulb. Some CF and LED bulbs are rated by the amount of light that an incandescent bulb would produce, but they are also rated by the wattage that they use.
Is speed of light faster than speed of shadow?
When we discuss moving faster than the speed of light, we are really talking... The speed of a shadow is therefor not restricted to be less than the speed...
How does a shadow travel faster than light?
The object casting the shadow moved, the source of light moved, the object upon which the shadow was cast moved, the shadow was viewed through a prism or a piece of glass that moved, stress or fear influenced the perception of the person seeing the shadow, some translucent or semi-opaque cloud or puff of smoke moved across the field and momentarily highlighted the shadow, or the shadow was never really there in the first place. There may be other possibilities, but they are not obvious to me at the moment.
Why does your body create a shadow?
Any opaque object which obstructs the path of light will create a shadow. For that very reason, our body, being opaque, creates a shadow when cast in front of a light source, such as, the sun.
