What is the height of the shadow when the distance from the light source to object is 24cm?

It depends what angle the light is at, for example the shadow would be longer if the light was looking atr the object from the side (45 degrees) than it would be if looking at it from the top of the object(180 degrees).

How does the distance between a light source and an object affect its 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.
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.
What affects was the size of a shadow?
The size of a shadow depends on, the angle that the light source is hitting the object and the size of the object. In some cases, the amount of light can also affect the size of a shadow.
Why do we have shadow?
Shadows are caused when an object is blocking the light causing the shape to appear on the ground in the opposite direction of the source of the light. A shadow only appears in the light or when any shining object faces them. All objects in the way of the light will appear with a shadow in the opposite direction of the source of the light.
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.
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 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 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.
How big can shadows be?
Size of shadow depends on its distance frm source of light.when object is vry clos 2 src of ligt the shadow formed is very big but when object is far , the shadow is small.
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.
Are shadow different sizes all the time?
The size of a shadow depends on the angle and distance if the light source and the size and shape of the object making the shadow. They can be the same size.
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.
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.
