Convex and Concave Lenses

Convex and Concave Lenses are Spherical Lenses. We look at the Image Formation by these spherical lenses using ray diagrams. Light ray rules for Convex Lens and Concave Lens are discussed. Using these rules we can find the position and properties of the image. I'll be the object in this video and you need to find my image!

1) concave lens.
2) convex lens, Between F1 and o ( optical center of the lens).
3) convex lens, position of the object should be at 2F1 and position of the image is at 2F2.

[ahmadmaaruf]

I really appreciate your style of imparting knowledge. Here are the answers of questions.
1. Concave lens
2. Convex lens and the object should be placed f1 and optical center
3. Convex lens
Position of object = 2f1
Position of image = 2g2

[dunno]

He explained them very clearly and understandable in just 18 minutes thought I'm gonna spend an hour or hours researching this

[Darkblade]

Q1. Concave lens
Q2. Convex lens is used and the object should be places between optical center and F1
Q3. Convex lens and position of object is at 2F1 and position of image is at 2F2

[aarushidubey]

17:27 Q1 Concave lens
Q2 Convex lens paced between optical center and focus
Q3 Convex lens and object is placed at 2F1.

You are doing a great job sir thank you so much.

[soham_editz]

Q1: concave lens
Q2: convex lens . Object between optical centre and F1
Q3: convex lens. Object at 2F1 and image at 2F2.
Thank you sir
U explain well. I like it

[vikramsingh]

Ans1-concave
Ans2-convex
Ans3-the lens is convex and position of object -(2F1)
Image-(2F2)

[novanovu]

Q1 concave lens
Q2 convex lens and it should be placed btw optical centre and F1
Q3 Convex lens and position is at 2F1 object and 2F2 image

[vanithakumarr]

1. Concave lens
2. Convex lens, between F1 and O
3. Convex lens
position of object - 2F1
position of lens - 2F2

[captainsparlez]

The reason that I'm liking physics is your explanation.

[Paramdeepsinghjatt]

1) concave lens
2)convex lens, between F1 and
optical centre
3) convex lens, object position
at 2F1 and image position at 2F2

[varalakshmi]

Q1:concave lens
Q2:convex lens is used in magnifying glass.object should be placed between F1 and optic center
Q3: convex lens.
Object is at 2F1

[akhil]

What an amazing explanation sir. I am really proud of you sir. I really understood what you said in this video. Keep it up 👍 sir.
Q1==> CONCAVE LENS.
Q2==>CONVEX LENS and the object should be placed between O and F1.
Q3==>CONVEX LENS, object at 2F1 and image at 2F2.

[jigishatalati]

answer no.1- concave lens
answer no.2- convex lens
answer no.3- the lens is convex lens and the position of object is at 2f1 & the position of image is at 2f2
Really Helpful sir
extraordinary explanation sir!!!

[princy_saini]

Only because of u now I'm in love with physics 😊hats off to ur efforts sir

[kaeya]

Q1/ Concave lens
Q2/ convex lens, the object should be placed between optical center and F1
Q3/ Lens → Convex
The object is placed on 2F1
The image is placed on 2F2

[deepikam]

I'm in class 12 now, and here to clear my basics. I used to watch your lectures when I was in class 10.
Thank you sir..❤️

[iromanandidevi]

Q1- Concave lens
Q2-Convex lens and between F1 and O
Q3 - convex lens and position of object-2F1, position of image-2F2

[NepaliDeepmind]

Here's what I comment:
Q¹. Name the lens that always forms a virtual, upright and diminished image.
Ans: It is concave lens that always forms a virtual, upright and diminished image.

Q². Which lens is used in a magnifying glass and where should the object be placed?
Ans: It is convex lens which is used in a magnifying glass & the object should be placed in between the focus and the optical center of the convex lens.

Q³. An object of height 5 cm is kept in front of a lens. An inverted image of height 5 cm is formed. Identify the lens & position of the object & image.
Ans: It is convex lens. The position of the object & image is 2F (2 times the focus, F).

Sir, your video is really highly informative and practical. Thank you so much, Sir. Commented with ❤️ from Dharmendra from Nepal. Hare Krishna🌹🌹🙏🙏
