How will you distinguish cast shadow from form shadow?
Answer and explanation
Correct answer: Cast shadow is the shadow an object throws on another surface
The governing concept is the difference between an attached shadow and a thrown shadow. A form shadow remains on the object itself: for example, the side of a sphere turned away from a lamp becomes darker. A cast shadow is projected by the object onto another surface, such as the dark shape of a vase falling on a table or wall. Its position and length depend on the light direction, the object’s height, and the receiving surface. Option D is correct because it defines this projected shadow accurately. Option A describes form shadow, B confuses shadow with light, and C is wrong because cast shadows are created by light being blocked.
