Can you explain the reason behind it

#Light #FUN #Explanations

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.

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

Aritra Jana - 6 years, 7 months ago

Yes @Aritra jana

U Z - 6 years, 7 months ago

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.

Robert Haywood - 6 years, 7 months ago

Wonderful it is...very cute.!

Sandeep Bhardwaj - 6 years, 7 months ago

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

Krishna Sharma - 6 years, 6 months ago

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

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.

Amanda Cabrera - 6 years, 7 months ago

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

satyam singh - 6 years, 6 months ago

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

Siddharth tiwari - 6 years, 7 months ago

yes got it right

U Z - 6 years, 7 months ago

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

Roshan Singh - 6 years, 6 months ago

nice question

pankaj tyagi - 6 years, 6 months ago

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

tushar kaushik - 6 years, 6 months ago

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!

Marc Vince Casimiro - 6 years, 6 months ago

internal total reflection

Arindam Biswas - 6 years, 7 months ago

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

Chiranjeev Mishra - 6 years, 7 months ago

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

Anuj Shikarkhane - 6 years, 7 months ago

On the right track just worded oddly.

Amanda Cabrera - 6 years, 7 months ago

Its a mirror
