A wooden block casts a/an ____ as it is _____.
- Image, opaque
- Shadow, opaque
- Image, transparent
- Shadow, translucent

The correct answer is: Shadow, opaque
¶- Transparent Objects: If you are able to see clearly through an object, it is allowing light to pass through it and is transparent. For example: water, clear glass etc.
¶- Opaque Objects: If we cannot see through an object at all, it is an opaque object. For example: wooden door, wall etc.
¶- Translucent Objects: There are some objects through which we can see, but not very clearly. Such objects are known as translucent. For example: Butter paper, ground glass etc.
¶- Opaque objects cast shadows because they do not allow light to pass through them. Hence, they form a dark patch on the other side of the object.
