Question: Suppose you have sunlight shining on two clear containers of water on a table. Light waves refract through one of the containers but diffract around the other container. Describe how the two containers are different.

(I have to write three lines, it's not a lot)

Please help me! I'm in 8th grade. Something simple, my book doesn't have the answers and all I the help I have found has a too high level.

sadly i need help as well, three years later, and my textbook also doesn't help at all. i can't find anything.

Wow

4 years later and still no answer
my book isn't helping either
books continue to prove useless and people wonder why we use the internet for everything

Sure! In this scenario, the two clear containers of water are different in terms of how the light waves interact with them. When light waves pass through one container, they undergo refraction. Refraction is the bending of light as it passes from one medium (air) to another (water) due to a change in speed. As a result, the light waves change direction when entering or exiting the container.

On the other hand, the light waves diffract around the second container. Diffraction refers to the bending or spreading out of waves as they encounter an obstacle or pass through an opening that is comparable in size to their wavelength. Here, the light waves are not significantly changing direction as they encounter the container but rather spreading out or bending around it.

Therefore, the difference between the two containers lies in how the light waves behave when passing through them.

It's normal that your book does not have the answers.

However, it's time to review the topics "refraction" and "diffraction" with the help of your book.
