Question

Statement 1: Shadows are obtained on the screen where light falls.
Statement 2: Size of the shadow can be different from the size of the object.
Which of the following is correct?

• A. Statement 1 is true but statement 2 is false.
• B. Statement 1 is false but statement 2 is true.
• C. Both the statements are true.
• D. Both the statements are false.

Answer 1

The correct option is B Statement 1 is false but statement 2 is true.

When light falls on an opaque object, the region behind it is devoid of light which leads to shadow formation. When we see the screen, only the part where light is falling is illuminated. The part where light is obstructed on the screen is seen as a shadow.

Size of the shadow depends on the size of the object, but may not be equal to it. It depends on multiple factors like distance between the object and the source of light, distance between the object and screen, etc.
