49:55, sir, the question doesn't instruct to inform about the mirror in detail. The question asks to sum up four observations or understandings from the given statement about the image/mirror.
In the second question the line marked as normal is actually principal axis and the light ray is bending away from normal i.e moving from denser to rarer.
Hello sir, I am Yash Jain. I have a doubt related to physics(human eye and the colourful world), as we all know because of scattering of light, the sun's ray's light appears to be yellow, but in actual the sun's ray's lights are of white colour, but why, when the light which is coming from moon at night doesn't appears to be yellow?

Thx

O bhai mujha to pta hi nhi tha yar
Aab pata chal gaya 😂
54:15 after seeing this question i was like:- ohh bhai yeh toh vedantu ke sir ne bhi karaya tha 😂😂😂
Sir 1:34:00 the lcm of 10,15 is 30 not 150 so v=-15 not -30 … btw u are the bestest sir 💖
Bro nhi sahi kra ha agar 30 LCM lenge to dekho...
1/-10= 1/v + (-1/15)
1/-10 = 1/v - 1/15
1/-10 + 1/15 = 1/v
Take LCM 30 then...
=-3+2/30
= -1/30 = 1/v
Therefore... V = -30
Clear bruda... ❣️❣️

39:55 Lateral Inversion is the property of a mirror which shows left side of the object right and vice versa when image is formed.
52:09 😮😮😮
All concepts clear sir.... 🔥🔥🔥🔥🔥🔥 thankyou so much... Sir 😇☺☺
Hi
49:57 he said image is virtual and erect but when magnification is in minus the image is real and inverted. 49:59
Ya bro
53:01
The ratio will be negative 1 (-1)
Because AB will behave live convex mirror, Its focal length will be psoitive
CD will behave as concave mirror
Its focal length will be negative
-f/f=-1
No bcz it is asking ratio
1:39:33 😮
3:44 convex lens
11:56 the magnification of the image will be unity bcoz image formed by plane mirror is same size of an object
laterally inverted means that image formed by mirror appears in the opposite direction of the object
ex: AMBULANCE
1:27:15 Height of image should be -2

It is maybe wrong
Because concave lens having focal length 0.25
Is -0.25 because it is concave mirror
So
P=1/f
-4= 1/-0.25
So is is right 👍🏻
But focal length sarre options mai +ve aur same hai, -ve kaha hai?
Maja aa gya sir thanku ab fir sa 1 baar khud sa sab question banaunga ☺️
39:57 visa versa of image

Hii
@Palak Rajput To fir ye bta do
List four precautions which a student should observe while determining the focal length of a
given convex lens by obtaining an image of a distant object on a screen.
@ʀᴏʜɪᴛ yes bro mistake ho gya
49:55, sir, the question doesn't instruct to inform about the mirror in detail. The question asks to sum up four observations or understandings from the given statement about the image/mirror.
That question was solved totally wrong.
If it is -3 ...then the image must be real, inverted & enlarged .
Best physics mentor hence proved.
magnification of spherical mirrors is -v/u

sir, in 24:02 can't we do it by the formula?

50:52 sir the image formed is diminished as m
It's enlarged since 3>1
If it comes anything between -1 to 0.10, then only its diminished
It's -3
I think it's m= 1 then it's same size m>1 then enlarged and m
Or does -ve doesn't matter at all
