Question

1.Why light is important?
2Explain the difference between opaque,transparent and translucent.

Answer 1

1. Light is important because it allows us to see things and is necessary for photosynthesis in plants.

2. Opaque objects do not allow light to pass through them and do not allow objects behind them to be seen. Transparent objects allow light to pass through them and allow objects behind them to be clearly seen. Translucent objects allow some light to pass through them, but objects behind them are not clearly visible.
