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

The closer to the light source an object is, the bigger the shadow will be. This is because the object blocks more of the light. The further away from the light source an object is, the smaller the shadow will be. This is because the object blocks less of the light.

What causes a double shadow?

To get two shadows from one object, you need two light sources; either two real sources of light, or effectively two sources because of some kind of reflection. The reflection of the nightlight from a mirror could act as a second light source, creating a second shadow.

What can a shadow tell you about the size of the source of light?

All light sources emit light waves that travel away from them. The closer an object is to the light source, the larger the shadow it casts. This is because an object closer to the source will block a larger area of the light, increasing its shadow size.

What is the relationship between the size of the shadow and the distance of the screen on which the shadow is formed?

As the object moves closer to the light source, shadow size on screen increases. Hence , shadow size is inversely proportional to the distance of object from the light source..

How do you relate the changes in position and length of shadows with the position of the sun?

When we are outside on a sunny day, we can see how our shadows change throughout the day. The Sun’s position in the sky affects the length of the shadow. When the Sun is low on the horizon, the shadows are long. When the Sun is high in the sky, the shadows are much shorter.

Why do I have 4 shadows?

There will be as many shadows as the number of light sources. People who play on playgrounds during night time or indoors where lights are switched on have 4 shadows (or any number of them ) because presumably there are 4 lights (or a number of them) pointed at them from 4 (or several) different directions.
