Can explain y? Thanks
Is correct answer 2?
All sheet cut out the same height.
1. Sheet P near to light source and furthest away from screen, it has largest shadow. Bigger than sheet Q and R. Big circle light at screen.
2. Sheet Q, light can pass through, so still big circle light at screen.
3. Sheet R with triangle cut out and no light pass through, further from light source and nearest to screen, will have smaller shadow/ light image on screen.
