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
Excellent!! All your answers are correct :) Also try the Quiz for this video on my Website. Quiz button is below the video: www.manochaacademy.com/physics/light/l/convex-and-concave-lenses
Q1 - Concave lens Q2- convex lens Q3- the lens is - convex And the position of the object - at 2f1 And the the position of the image is at 2f2 I learnt a lot from you thank you sir ☺️
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.
My teacher used your video to teach us this concept and all of the students understood it well. I have physics exam tomorrow and I am shure that because of your great demonstration, I will get full marks in reflection of light
1-) concave lens 2-) convex lens object should be placed closer to the lens 3-) convex lens position wil be on 2f2 and image will be formed on 2f1 which is an inverted real and same sized image
Thank you so much for printing the concept in my brain 🙏🙇♀️ 1. Concave 2.convex , between Focus( f1) and optical centre 3.convex , on the centre of curvature (2f1) Not concave because it produces virtual and upright image
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
1) concave lens will always form a virtual, erect/upright and a diminished image. 2) convex lens is used as a magnifying glass, it must be place between the focal length (F1) and the optical centre to have a very magnified , virtual and an erect image. 3) since image size is the same as the object size, that means the lens is a convex lens and the object is place on the principal focus (2f1) likewise the image would be formed on the principal focus (2f2) .
Whenever I have difficulty on understanding topics in physics, I always look for an explanation from your channel, Sir. I just recently found out about your channel and since then I wish you have the explanations about difficult topics You are a great teacher, thank you. More power!
Answer of the questions 1. concave lens is always form virtual ,erect and diminished image 2. Convex lens is used in magnifying glass and object should be placed between 2f1 and f1 3. According to the given situation, the object is placed in the front of convex lens at 2f1 and the image formed at 2f2
Answers:- 1) Concave lens 2) In convex lens and the object should be placed between F1 and optical center 3) the lens is convex lens and the position of the object is at 2F1 and the position of the image is at 2F2 (as m=-1=v/u; -u=v)
Hats off to you sir.. I hated this topic bcoz it was a difficult topic for me.. But now I'm at ease like we all enjoyed this topic bcoz of the amazing representation.
1 ans: concave lens 2ans: convex lens . Object should be placed between F1 and o . 3ans : It is a convex lens. The object is placed on the 2 F1 of height 5 cm . The image is invented , real, equal to the object height , and formed at 2F2
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.

Answer 1: Concave Answer 2: Convex and it should be placed between F1 and O Answer 3: Convex and the position of the object should be placed on 2F1 and the position of the image should be 2F2
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
I've been trying to learn this for sooo long, thanks for breaking it down!❤ Also, I solved the questions and got them(hashtag shook!😂): 1. Concave lens 2. Convex lens and it should be placed between 2F2 and F2 3. Convex lens and the object is at 2F2, the image is at 2F1
Q1: Ans ;) Concave lens Q2: Ans;) Convex lens and placed the object at the away from lens. Q3: Ans;) Convex lens and postion is F2 and image is real. Thanks 😊 Lōve from Pakistan 🇵🇰❤️🩹
