Why was object changing its size in ray diagram of concave mirror? (Isn't it surprising?)

-




You're absolutely right! It can be surprising and even counterintuitive to see the object size seemingly changing in ray diagrams for concave mirrors. While the actual object remains the same size in reality, its **representation in the diagram changes** depending on its position relative to the mirror.


Here's why it might seem awkward:


1. **We're used to perceiving size consistently:** In our daily lives, objects have fixed sizes regardless of their distance from us. However, ray diagrams are simplified representations that emphasize light rays and their interaction with the mirror, not necessarily object size.


2. **The object symbol represents actual location:** In ray diagrams, the object is often represented by an arrow, with the arrowhead indicating its actual location. The length of the arrow doesn't necessarily reflect the object's size, but rather its position relative to the mirror.


3. **Focus on ray behavior:** The primary purpose of ray diagrams is to visualize how light rays bend and interact with mirrors or lenses, leading to image formation. The object size plays a role in determining the image size and characteristics, but its representation in the diagram serves as a reference point for the light rays, not a depiction of actual size.


While it might seem strange at first, understanding that the **object representation in the diagram is symbolic, not a scaled depiction of its actual size**, is crucial for interpreting ray diagrams correctly. They are powerful tools for understanding light behavior and image formation, but it's important to remember their limitations and focus on the underlying principles they illustrate.


If you have any further questions or would like to explore specific diagrams where the object size seems to change, feel free to share them! I'm happy to help you navigate the seemingly awkwardness and delve deeper into the fascinating world of ray diagrams.

This speech was written by Mohit, it was delivered on the occasion of National Youth Day at FIS (Manasa).     Speech Swami Vivekananda, in his childhood he was called Naren, was born on January 12, 1863 in Kolkata. His father, Vishwanath Datta, was an advocate in the High Court of Kolkata. Vishwanath had a deep interest in music and he thought of it as the source of much innocent pleasure. He used to read Bible and recite poems of Persian poet Hafiz with great joy. Naren's mother, Bhuvaneshwari Devi, was extraordinarily intelligent and it was her habit to study Sanskrit scriptures the Ramayan and the Mahabharata.     When Naren was studying in sixth class of Pandit Ishwar Chandra Vidyasagar's Institution, he was told that he would have to study English. He was not willing to do so. It was a foreign language, he said, so why should he learn it? The teachers persisted and Naren went home crying to his parents and there his father made him aware about the Joy of Learni...

How did Bhagat Singh join HSRA? (DeepSeek)

 Bhagat Singh's association with the Hindustan Socialist Republican Association (HSRA) was a pivotal chapter in India's freedom struggle. Here's a detailed account of his journey into the organization: --- Early Influences and Political Awakening 1. Family Background:      Bhagat Singh was born into a family deeply involved in the independence movement. His father, Kishan Singh, and uncle, Ajit Singh, were active revolutionaries, exposing him to nationalist ideas from a young age. 2. Impact of Jallianwala Bagh (1919):      The massacre at Jallianwala Bagh in 1919, when Bhagat Singh was 12, radicalized him. He openly defied British authorities by burning textbooks and symbols of colonial rule. 3. Rejection of Non-Violence:      Disillusioned by the slow progress of the Indian National Congress' non-violent methods, Bhagat Singh gravitated toward revolutionary ideologies. He famously said, *"Bombs and pistols do not make a r...

अज्ञेय जी कहते हैं ‘मेरा सच्चा पाठक वही है, जो मेरा लिखा हुआ समझे और उसके अनुसार कर्म करे।’ शेखर को लगता, उसके शरीर में कोई परिवर्तन हो रहा है। उसे लगता, वह बीमार है; उसे लगता, उसमें बहुत शक्ति आ गयी है; और वह, अपनी दुम का पीछा करते हुए कुत्ते की तरह, अपने ही आसपास चक्कर काटकर रह जाता...      अपने शरीर की माँग वह नहीं समझता, लेकिन उसे लगता, यह माँग कुछ अनुचित हैै, कुछ पापमय है। और वह चाहता कि किसी तरह उसे दबा डाले, कुचल डाले, धूल में ऐसा मिला डाले कि उसका पता भी न लगे, चाहे शरीर ही उसके साथ क्यों न नष्ट हो जाय...      वह मन उस पर से हटाना चाहता। यह तो वह जानता नहीं था कि किस तरह से शरीर से मन हटाए, लेकिन कविता में रुचि थी, और इसलिए उसे आशा थी कि वह उसमें अपने को भुला सकेगा। वह हर समय, हर प्रकार की कविता पढ़ने लगा। उसने संस्कृत-कवि पढ़े, उसने उर्दू से अनुवाद पढ़े, उसने जो कवि उसकी पाठ्य-पुस्तकों में थे — Tennyson, Wordsworth, Shelley, Christina Rossetti, Scott — सब पूरे पढ़ डाले। फिर उसने वे कवि पढ़ने आरम्भ किये, जो उसकी पुस्तक...
