Transparent objects do not cast shadows.

Answer

To determine whether the statement "Transparent objects do not cast shadows" is true or false, we can analyze the properties of light and how shadows are formed. Here’s a step-by-step solution:

### Step 1: Understand what a shadow is
A shadow is formed when an object blocks the path of light. The area behind the object, where the light cannot reach, becomes dark, creating a shadow.

**Hint:** Remember that shadows are created when light is obstructed.

### Step 2: Identify the types of objects
There are two main types of objects concerning light:
- **Opaque objects:** These do not allow light to pass through. They block light completely and cast shadows.
- **Transparent objects:** These allow light to pass through them. They do not block light and, therefore, do not cast shadows.

**Hint:** Think about how different materials interact with light.

### Step 3: Analyze the behavior of light with opaque objects
When light hits an opaque object, it cannot pass through. The area behind the object where the light is blocked will be dark, resulting in a shadow. The shape and size of the shadow depend on the shape of the object and the angle of the light source.

**Hint:** Consider what happens when you place an opaque object in front of a light source.

### Step 4: Analyze the behavior of light with transparent objects
When light encounters a transparent object, it passes through without being blocked. Since the light continues to travel beyond the object, there is no area where the light is obstructed, and thus, no shadow is formed.

**Hint:** Visualize how light travels through glass or clear plastic.

### Step 5: Conclusion
Based on the analysis, we can conclude that transparent objects do not cast shadows because they do not block the light. Therefore, the statement "Transparent objects do not cast shadows" is **true**.

**Final Answer:** True
