MCQ Assessment
HOTS Questions
1. Why is a periscope useful in a submarine?
It allows people inside the submarine to see objects above the water surface.
2. How would life be different if light did not reflect from objects?
We would not be able to see objects because reflected light enables vision.
3. Why are microscopes important in medicine?
They help scientists and doctors study tiny organisms and cells.
4. How has the telescope changed our understanding of the universe?
It allows astronomers to observe distant stars, planets and galaxies.
5. Why is refraction important in making spectacles?
Lenses bend light to help focus images properly on the retina.
