Question

The diagram shows the length of shadows formed when the same object is at different positions
between the light source and screen. How does the length of the shadow vary with the distance o
the object from the source of light?​

Answer 1

Answer:

How do the length and the shape of the shadow change with the position of the source of light with respect to the object. IF THE DISTANCE BETWEEN THE OBJECT AND SOURCE OF LIGHT IS DECREASED IT APPEARS TO BE LARGER . IF THE DISTANCE BETWEEN THE OBJECT AND SOURCE OF LIGHT IS INCREASED IT APPEARS TO BE SMALLER

Explanation:

Technically, like any non-transparent object, the Sun would cast a shadow on another object. However, since the Sun emits light itself, it would only result in a true shadow if there were a stronger level of illumination on that object coming from a source behind the Sun.
