SUMMARY

The discussion centers on calculating the apparent displacement of an object submerged in water, specifically using the principles of optics and Snell's Law. The formula for determining the apparent depth, which accounts for the refractive index of water, is provided through a link to Physics Tutorials. Participants emphasize the importance of understanding the relationship between real depth and apparent depth, especially for practical applications like fishing. Mastery of these concepts allows for accurate predictions of object positioning when viewed through water.

PREREQUISITES
  • Understanding of Snell's Law in optics
  • Familiarity with the concept of refractive index
  • Basic knowledge of geometry related to angles and depth
  • Ability to apply formulas in practical scenarios
NEXT STEPS
  • Research the derivation of Snell's Law and its applications
  • Explore the relationship between real depth and apparent depth in various mediums
  • Learn about the refractive index of different liquids
  • Study practical applications of optics in fishing and underwater observation
USEFUL FOR

Anyone involved in fishing, optics enthusiasts, physics students, and professionals needing to calculate object displacement in fluids will benefit from this discussion.

hi everybody, suppose we are viewing an object in a pool whereby the object is actually at the bottom of the pool, ...so it will appear as if it has been displaced. what formula can we use to calculate the displacement of the object...??
are there any conditions applicable..help me with this detail please

Are you a frustrated harpoon fisherman? I have spent ages trying to spear fish from the side of a boat. The Maths is not hard -
http://www.physicstutorials.org/home/optics/refraction-of-light/apparent-depth-real-depth" gives you the formula but it's hard to work it out on the fly and amidst the excitement of a massive Grey Mullett going past.

nah man, there do have a formula related to the refractive index...
 
It's on that link for you to use at your leisure. The formula gives both the new angle and the new height. But, if you know Snell's Law, you should be able to derive it for yourself. At least, their derivation makes easy sense.

I'll get back to my fishing when my future son in law buys a new harpoon to replace the one he chucked over the side by mistake.
