Read the given statements and select the correct option.Statement 1 : ...
Statement 1: Rahul placed a coloured plastic bottle in front of the beam of a torch light. Then he placed a transparent sheet of same size on the other side of the bottle. No shadow will form on a screen placed behind the sheet.
When Rahul places a coloured plastic bottle in front of the beam of a torch light, the light passes through the bottle. However, the bottle absorbs some of the light and scatters the remaining light in different directions. As a result, a shadow of the bottle is formed on a screen placed behind it.
When Rahul places a transparent sheet of the same size on the other side of the bottle, the light that passes through the bottle will continue to pass through the sheet as well. This means that the light will not be blocked or scattered by the sheet. Therefore, when a screen is placed behind the sheet, no shadow will be formed.
Statement 2: Translucent objects allow light to pass through them partially.
Translucent objects are those that allow some light to pass through them, but they also scatter and absorb some of the light. This means that when light passes through a translucent object, it is not completely blocked or completely transmitted. Instead, some light passes through while some is scattered and absorbed.
Explanation:
The correct option for this question is D) Statement 1 is false but statement 2 is true. Here's why:
- Statement 1 claims that no shadow will form on a screen placed behind the transparent sheet when a coloured plastic bottle is placed in front of the beam of a torch light. However, this is not true. When the light passes through the bottle, it will be scattered and absorbed, resulting in the formation of a shadow on the screen.
- Statement 2 is true. Translucent objects do allow light to pass through them partially. They scatter and absorb some of the light, but they also transmit some of it. This is why we can see objects on the other side of a translucent material, although they may appear blurry or less distinct.
Therefore, statement 1 is false, as a shadow will form on the screen when the transparent sheet is placed behind the coloured plastic bottle. Statement 2 is true, as translucent objects do allow light to pass through them partially.
