Which option represents Transmitted (back lighting)?

• A. Oblique (side lighting)
• B. Long Wave UV Light
• C. Front lighting
• D. Transmitted (back lighting)

Answer: (D)

Transmitted (back lighting) means you place the light behind the object so the beam passes through it toward the camera. This makes translucency and internal details visible, which is useful for examining thin or transparent materials like fibers, glass, or liquids in a container. Front lighting would illuminate the surface from the viewer’s side and often minimize internal features; oblique (side) lighting creates shadows to reveal texture, and Long Wave UV Light is used to induce fluorescence rather than simply illuminate through the object. So the description that involves light coming from behind and passing through the subject best matches transmitted (back lighting).
