Ma'am I have a doubt what if we take the concave mirror's aperture towards the positive side. 1.Will sign remain same 2. is it compulsory to have the aperture always facing towards negative side on a Cartesian plane? Same for convex ??
I was searching for this formula to understand but everywhere they were making it very complicated And it was hurting my head Thanku mam for this beautiful and easy explanation 💜💜
Can you tell me how you at 15:07 she took the object at center it's not even given in the question so how and the object distance is given 25 cm so should the [u] be 25? I am honestly soo confused 🥲🥲
@@aksa.3 Sis , I think you should pay more attention to the video because she wasn't explaining that que,she was just proving that 'if the object is placed at centre of curvature then the image will also be formed at centre of curvature in concave mirror'.

Hi there! We're glad you're taking the time to watch our educational videos! The answer to your question is at 15:07, she took the object and moved it to the center of the circle. The object's distance is given as 25 cm, so it should be 25. We hope this helps! If you have any other questions, please don't hesitate to ask. Thanks for watching!

Yaa
Nice
Saach he bhai
In a first numerical
We have to find out of image
1/u + 1/v = 1/f
-1/25 + 1/v = 1/15
1/v = -1/15 + 1/25
Multiplying 15 × 25 = 75
1/v = (-5 +3)/75
1/v = -2/75
V= 75/2
Divide the 75 and 2 = 37.5
Find out the height of the image and height of the object
THE TOTAL ANSWER = -6cm
Thank you so much for teaching as
It was so clear and good 🙏🙏
Learning from UA-cam is much more better than learning in school
Or tutions😂😂😂😂😂😂🎉🎉🎉🎉🎉🎉❤❤❤❤❤❤❤
