Explanation:
Introduction:
Shadows are formed when an object blocks light from a source, creating a dark area behind it. In order for an object to create a shadow, it needs to be opaque or partially opaque, allowing it to block the light.
Analysis:
Let's analyze the given objects and determine whether they can create a shadow or not.
a) A ball of yarn:
A ball of yarn is soft and made up of threads. It is not an opaque object, and light can easily pass through its gaps. Therefore, a ball of yarn cannot make a shadow.
b) A rubber duck:
A rubber duck is a solid object and is partially opaque. It does not allow light to pass through it completely. Therefore, a rubber duck can make a shadow.
c) A fluffy pillow:
A fluffy pillow is soft and made up of fabric. It is not an opaque object, and light can easily pass through its fluffy surface. Therefore, a fluffy pillow cannot make a shadow.
d) A cardboard cutout:
A cardboard cutout is a solid object and is opaque. It blocks light from passing through it, creating a shadow behind it. Therefore, a cardboard cutout can make a shadow.
Conclusion:
Out of the given objects, only a cardboard cutout can make a shadow. It is important to note that for an object to create a shadow, it needs to be partially or completely opaque, blocking the light from the source.
