Observe the picture given in figure A sheet of some material is placed at position ‘P’, still the patch of light is obtained on the screen. What is the type of material of this sheet?
Screen
Source of light
Open in App
Solution
Step 1: Observation
The sheet is placed perpendicular to the right rays.
From the figure it is clear that the intensity of light is reduced after refraction from the sheet.
The image is formed on a particular screen.
Step 2: Diagram
Step 3: Explanation
Light rays passed through sheet P due to refraction and then transmission. And after this, the light rays formed an image on the screen.
From the figure, we can say that the given sheet P is a transparent material. Because light rays can penetrate transparent sheets.
P might be transparent material like - thin glass, clear plastic paper, etc.
Therefore, the sheet is a transparent material like - thin glass or a clean plastic sheet.
