I am a student of aakash+byjus and my father paid 1lakh rupees for me but in aakash no someone worry whatever students are doing, the teachers did not think about students they want only to complete their job the quality of aakash is world's worst teaching. Before the joining aakash I am a top ranker student but after joining aakash my progress gone down wards. I am regreting why I joined aakash . But PW is the most wonderful platform i maintained my score by the PW teachers . , even my english default can explain aakash teaching. I really love PW Thanks my PW teachers and this wonderful platform ❤.
@@clasherayushgaming3488I also go to akash and trust me it's great , you just need to learn to utilise the resources . If you have extra doubts just go at any time find the teacher and ask the doubt it's as simple as that. And if the teachers are not good just complain...it's that easy

3:22:36 Sir apne jo concept padhai woh sirf covex lens mein hota hai, concave lens mein optical centre se jab light jati hai woh normal nhi hoti, waha refraction hota hai 2 times aur light ray bahar nikalti hai woh thodi laterally displaced hoti hai but usually hum ye assumption manke chalte hai ki hamne jo concave lens liya hai woh itna thin hai bich mein ki lateral displacement negligible hai.
Actually sir you have made a mistake in image formed by concave mirror in 6th case if incident ray is parallel to principal axis then reflected ray will stop by object as it is opaque . ❤❤
33:27 No, they can not form real image 39:37🔥🔥🔥🔥 Characteristics of image formed by plane mirror: 1. Virtual and erect 2. Height of object= Height of image 3. Laterally Inverted 4. u=v
The speed of light in air is approximately 299,792,458 meters per second, which is the same as its speed in a vacuum. However, it may vary slightly depending on factors like the composition and density of the air.

Sir in the last question of [refractive index topic] frequency of light in the block can also be find by finding the frequency of light in air medium as frequency is constant and never changes after an refraction and the frequency would become 6 x 10^5 m/s is this can be correct solution ?????
Sir, you teach very well👍 but I think you have made a mistake here. 1:05:56 In the sixth case of concave mirror, you have drawn the first ray parallel and passes through the focus, but this will not be practically pass through the focus. Because the light ray is stopped by our object and its light track is placed across the object. then the curvature rule will apply there Thanks for this ☺️🙏 sir
@@amitsahni629 Bhai answer same hi aya ga per jo sir na first ray draw ki ha focus sa pass Kari ha wo practically light ray object ma sa kasa nikal sakti ha 😅

@radhikavii-a2102 kya hogya ?
03:29:51 real inverted kaise hogi jab meet nahin kar rahi actually doubt hai please solve
Voh infinity pe meet karengi(very far away).par kahi pe meet karein ,in real life woh real aur inverted hongi.
3:48:17 Hi=-3.3,v= 50/3cm,m=-0.66cm, real and inverted ,diminished and for extra it is the case when object is placed beyond 2fi
Same answer aagaye Bhai lekin m=-ve he ek bar check kardo
Yes magnification negative me hai
hi = -3.3cm
m=-0.66
v=16.6 cm
Magnification unit less hota hai sir ne vedio me bataya ....
Bhai galat answer hai
Correct answer 👇🏻
M=-1.5
V=16.6cm
Hi=-7.5cm
Magnification -ve matlab real inverted and 1 se jyada he matlab enlarged

3:22:36 Sir apne jo concept padhai woh sirf covex lens mein hota hai, concave lens mein optical centre se jab light jati hai woh normal nhi hoti, waha refraction hota hai 2 times aur light ray bahar nikalti hai woh thodi laterally displaced hoti hai but usually hum ye assumption manke chalte hai ki hamne jo concave lens liya hai woh itna thin hai bich mein ki lateral displacement negligible hai.
best of luck exam k liye
I literally can't believe that I understood this chapter without a single problem for the first time. Thankyou so much Rakshak sir 😭🫶
Sir Which lens/mirror is used in projectors?
@@JayniMiteshPatel Convex lens
Yes it's true 🙄
24:31 ... sir if the image formed in theaters is real, why is it not inverted acc. To the property?
4:01:03 Homework question
P=0.5D,f=2metre.
Bhai Mera toh p = -0.25 or f = -400 cm AA Raha hai
Mera p= 0.5D and f= 200cm(in m=2)
Actually sir you have made a mistake in image formed by concave mirror in 6th case if incident ray is parallel to principal axis then reflected ray will stop by object as it is opaque . ❤❤

The speed of light in air is approximately 299,792,458 meters per second, which is the same as its speed in a vacuum. However, it may vary slightly depending on factors like the composition and density of the air.

Hii

Sir in the last question of [refractive index topic] frequency of light in the block can also be find by finding the frequency of light in air medium as frequency is constant and never changes after an refraction and the frequency would become 6 x 10^5 m/s is this can be correct solution ?????
no
thank you sm sir for continuing class for straight 4 hours hats off to you ❤
Sir, you teach very well👍 but I think you have made a mistake here.
1:05:56
In the sixth case of concave mirror, you have drawn the first ray parallel and passes through the focus, but this will not be practically pass through the focus.
Because the light ray is stopped by our object and its light track is placed across the object.
then the curvature rule will apply there
Thanks for this ☺️🙏 sir
You are right
no bro piche mila ha isliye to virtual image ha
@@amitsahni629 Bhai answer same hi aya ga per jo sir na first ray draw ki ha focus sa pass Kari ha wo practically light ray object ma sa kasa nikal sakti ha 😅
