Question

when completing a science lab on how light interacts with different objects, the teacher closed the curtains in the classroom to eliminate the light coming through the windows. even though the curtains were closed, some light was still able to come through.

1. why did some light still come through even though the curtains were closed?
2. what type of curtains should the teacher put up so that no light will come through them?

Explanation:

1. La luz puede filtrar a través de las cortinas si no son completamente opacas. Las cortinas pueden tener tejidos con agujeros pequeños o seres ligeramente transparentes, lo que permite que la luz se filtre.
2. Las cortinas opacas, como las de terciopelo o las recubiertas con un material impermeable a la luz, impedirían que la luz se filtrara.

Answer:

1. La luz puede filtrar a través de las cortinas si no son completamente opacas.
2. Cortinas opacas, como de terciopelo o recubiertas con un material impermeable a la luz.
