Question

Q6. In a dark room, take an opaque object such as a book/toy. Place a torch in front of the book/toy in such
a way that its shadow is formed on the wall. Now, keep the torch at different distances (near, far or very
far) from the object and observe the change in the size of the shadow. Explain these changes. (2)​

Answer 1

Answer:

Objects able to block all the light are called opaque and will form a shadow. ... The closer an object is to the light source, the larger the shadow it casts. This is because an object closer to the source will block a larger area of the light, increasing its shadow size
