What is the size of the shadow and the distance of the object from the light source when a shadow is formed?

If you are using a point light source, the shadow's size is the object's size divided by the distance from the light source to the object multiplied by the distance from the light source to the shadow.


what causes shadow length?

The length of an object's shadow is determined by ... -- the length of the object, -- the angle between the object's length and the surface on which its shadow appears, -- the distance between the object and the surface on which its shadow appears, -- the angular size of the light source as seen from the object, -- the angle between the direction to the light source and the normal to the object.


What is the relationship between the size of the shadow and the distance of the object from the light source?

The relationship between the size of a shadow of an object and the distance of light source from the object is indirectly proportional. A short distance will make the shadow big while making the distance long will reduce the size of the shadow.


What happen to the shadow if an object is closer to the source of light?

When object is closer to source of light ,the shadow formed of the object is shorter and darker.


What will happen to the colour of the shadow if a piece of blue cellophane paper is placed between the light source and the object?

Nothing will happen to the colour of the shadow. A shadow is the absence of light, and the object will still block the blue light.

Is there a relationship between the distance of the light source and the object?

The further the light source is from the object, the smaller the shadow formed and vice versa.


The closer the light source the shadow is what?

The closer the light source the larger is the shadow. You can understand this effect using the paraxial aproximation of light theory. If you draw lines from the light source to the edges of an object, there is an angle (call it alpha) between the these lines and the orthonormal vector to the object. The shorter the distance between the light and the object, the higher is alpha (because the height of the object is always the same): tan(alpha) = (height of the object)/(distance between light and object) Of course the relationship between the height of the shadow and the angle is the same: tan(alpha) = (height of the shadow)/(distance to the wall in which the shadow is proyected) So, the higher the angle alpha (and closer the distance between light and object), the heigher is the shadow.


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.

What factors affect the size of a shadow formed on a screen?

The size of the shadows formed changes if the distance between the object and the screen is also changed. If there is an increase in the distance between the screen and the object, the size of the shadow also increases.


What 3 things make a shadows?

A shadow is formed when an object blocks light, creating a dark area behind it. Three factors that determine the size and shape of a shadow are the angle at which the light hits the object, the size of the light source, and the distance between the object and the light source.


How could you change the size of your shadow?

You can either move closer to the light source or move the light source closer to you. The size of your shadow just depends upon how much of the light you are obscuring so the more you block out, the bigger your shadow.
