The Mirror Equation (Concave Mirrors)

[@kyler124]

You saved my physics grade

[@didi6272]

Some say heroes wear capes, they obviously were never failing physics. Thank you!!

[@애리츠]

If someone is also confuse on how did he got 22.5 just divide 1 by 0.0444 on your calculator :) it also took me a while lol

[@yorumeroesugeravtex4074]

Thank you so much

[@ethanmatthewapostol881]

mine is 2/45

[@rianjeskrystlamban]

how he got the 0.444

[@yorumeroesugeravtex4074]

@@rianjeskrystlamban he used a calculator, put 1/10 - 1/18 and you’ll get the answer

This is the only video I found that helped me. Thx

Light bulb in my head. Thanks for this.

[@jesiricornel7114]

what if were looking for the distance of the object and thefocal length .what equation and process to use?help please!thank you

[@nickguardiero8362]

This is an amazing video!!!! Make more plz

[@kianahekmat]

you taught this better than my physics teacher

[@justKubus]

0:42 the focal point isnt half of the radius its the center of curvature that is half

[@karlisle0]

Isn't the center of curvature = radius? If so, then the the focal point is = radius/2

[@Kimmy01034]

Omygod you literally save me, thanks sir. I hope you don't die 😚

hey i know this video is a bit old but i just finished watching it and i was wondering if the mirror equation work for a convex mirror

How did you convert the 0.0444 to 22.5?

[@earlchristianardemil9308]

Divide 1 by 0.0444

Great video! Thanks for the magnification formula! (:

Now, I'm stuck again it wants me to express in terms of f and s.

[@valm124]

Do you have a convex mirror video?

[@so.meYeah]

this is a good video..could you make a video on calculating focus of a concave mirror which is drawned in water (mu=3/4)

[@matthewsuarez6887]

can someone explain to me how to do the inverse thing on my calculator

[@Zebre86Cie]

take a number and take it to the power of -1 (usually a x-¹ symbol)

[@semonsingh1344]

I don’t get how get got 22.5 from 0.0444 Like how?

[@levinelevine7983]

I knowwwwww

[@kylepetrovic1296]

just put 0.0444 to the power of negative 1

[@cyrmichaeljosef8616]

Really helpful for a report thank you Sir!! did a great job explaining it!! really understood it!!

[@Green0rganic]

how to solve this question - draw a ray diagram of an object 0/75f from a concave mirror?

[@anterosia8152]

what if focal point isn't given? just obejct distance and height distance?

[@maricaranas]

i just wondering that how do you get that 11.3cm

[@애리츠]

5:01 sir my calculator said it's 11.25 is it always necessary to round off?

[@louiselabian3577]

How did u get it

[@애리츠]

@@louiselabian3577 22.5 x 9.0 = 202.5 then divide this to 18 you'll get 11.25

[@nationalistdiplomat8751]

I found this equation during my attempt to quantify the projection of a democrat upon a Republican, a common mental disorder found in leftists, yet one which is challenging to model. I think what is needed would be more in line with a mirror reflection which is projected upon a Republican and which solves by taking the projection and reflecting it back upon the democrat to understand what the democrat actually does or thinks. Can someone help me with a formula that effectively models this phenomena?

[@angelluce]

Dude is fluent in yappanese

[@henrytraylor137]

This really helped thanks

[@danrichwilliambabaran6833]

How did you get 0.0444? Because when i subtract 1 over 10 from 1 over 18 what i get is 0.0445

[@itsmeSmile]

nice vid but i wanted to learn how to derive mirrors formula

[@smcclyment]

Love it! Thank You

[@louiselabian3577]

How did u get the 11.3

[@vonsert9881]

I got a physics test in like 30 minutes. Thanks

[@zapboost1235]

how did he get the 11.3cm?

[@ansubadjie2381]

I’m sorry but did you tell us how the F you took the inverse of 0.0444‼️

[@AshtonNadon]

Ansu Badjie use the x-1 button on your calculator, or do: 1 divided by .0444 to obtain your final number for “di”

[@roseyyythorns7384]

Why is it. 0.444? 1/10 is 0.1 while 1/18 is 0.055? Then if you subtract it the answer would be 0.045?

[@ItzMeJohn]

1/10-1/18 = 0.0444 he divided 1 by 0.0444 to get 22.5cm

[@miguelcocal1209]

How did you get the 0.0444?

[@TheScienceClassroom]

It's the inverse of the image distance

how did he get-11.3 i didn't get that part only the last part i didn't get it

(Image distance x object height) ÷ object distance

HELP ME!!!!!!! HOW DOES HE GET THE 22.5 CM??????????? PLEASE!!!!!!!!!!

[@TrollNation]

1/10-1/18 =0.0444=1/di = 1/0.0444 he divided 1 by 0.0444

[@puppyfacespiderman3610]

TY.

[@spiousas]

Nice video. One Small detail: when you wrote "1/di = 22.5 cm", that is not correct.

[@daered]

Ignacio Spiousas yes it is

[@tanisharasealle8373]

Ignacio Spiousas 26.35 is the answer guys

[@kurotpisngi821]

how did you get that answer?

[@boredhooman-if4ik]

I am so confused on how he got -11.3cm- I keep getting -11.25cm instead in my calcu and from the google-

[@TheScienceClassroom]

11.25 is the correct answer but has the incorrect significant digits. I rounded it to 11.3 so that it only has 3 digits to match the given data.

[@sebastienjafari7129]

isnt that convex
