Optics: Real and Apparent Depth

In this video we will explain the concept of apparent depth, refraction of light and why things aren’t always where you think they are.

Best video out there for this topic, really appreciate your work

[@stepbystepscience]

So nice of you, thank you so much

[@mahibarot2828]

Thank you for great explanation! Could you please also make video on how to derive equation of apparent depth from snells law

[@stepbystepscience]

Great suggestion! I do have video about apparent depth but I do not actually derive the equation in the video....Sorry. kzbin.info/www/bejne/hqOxq3qmbrGKbbc

[@lmaolpha_male]

great vid! could you pls make one on errors in measurement, cause i always manage to forget it during my exam and another on how to use a vernier callipers?

[@stepbystepscience]

can you give me a little more detail or an example of what you mean by errors in measurement.

[@lmaolpha_male]

@@stepbystepscience calculating stuff like absolute, relative and percentage error, parallax errors, combination of errors(for eg, when we're given the values of two resistors( like 100 ± 3 and 500 ± 2 ohms) in parallel connection, and we need to calculate the net resistance, and the answer is in ± terms. other than that there's significant figures too, like the fact that 0.002304 has only 4 significant digits.

what if the viewer is on the bottom at 0.5 bellow the water and theres a lightbulb perpendiculary above with a hegiht of 1.5m

[@carnsoaks1]

What, first? OMG, thankyou!I can't believe it. OMG

[@stepbystepscience]

You are very welcome!
