Question

4 what happens when light is completely transmitted through an object?
a light rays change directions
b the brightness of the transmitted light increases
c light rays refract as they enter the object
d the object absorbs and reflects little to no light

Explanation:

To solve this, we analyze each option:

• Option A: Light changing direction is refraction or reflection, not directly related to complete transmission. Eliminate A.
• Option B: Complete transmission doesn't mean brightness increases; usually, some light is absorbed/reflected, so brightness wouldn't increase. Eliminate B.
• Option C: Refraction when entering is about direction change at the boundary, not about complete transmission through the object. Eliminate C.
• Option D: If light is completely transmitted, the object absorbs and reflects very little (since most light passes through), which matches the concept of transparent objects.

Answer:

D. The object absorbs and reflects little to no light
