This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .

Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.

Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Hmm... Water has been learning how to use PhotoShop? JK, obviously for such an image to appear, we'd need a converging lens, and I don't see anything else suspicious, so it must be the water.

Pysics... angle of incedence = angoe of reflection. The curved surface of the glass and the desnsity? Of water causes the light to bend more/differently then if it were traveling through air.

Thought it was about refraction when I say the water, but well physics is wide. Try using a ray diagram, awesome isn't it? Now since it is a concave mirror, try a convex one, you will get another awesome result!

TopNewestthe glass of water acts as a converging lens, which creates an inverted real image?

Wonderful it is...very cute.!

Due to cylindrical(curve) shape of water(thickness of glass neglected) image is inverted. Try a rectangular glass then arrows direction won't change!

Wow!! That is one of the beautiful reasons why i love science, lol!!

It is due to water.water acts as a converging lens and form invertered image.

Log in to reply

It is due to water, as water acts as converging lens, which gives us an Inverted Real Image..........

yes got it right

Log in to reply

When we filled water bcs of this the refractive index changes which act like a cylinderical lens and inverted image is formed

Log in to reply

nice question

Log in to reply

when the water is filled in glass then it acts as a converging lens which makes real and inverted image

internal total reflection

Log in to reply

After water is poured due to total internal reflection image is reversed

When we add water, because of water reflection, the left arrow seems to be a right arrow.

On the right track just worded oddly.

Its a mirror
