Full Classroom Lectures: Mastering Science and Maths Concepts
If you are looking for clear, whiteboard-style explanations that ditch rote learning, you are in the right place. Dive into our full-length lecture clips to master tricky topics in Physics, Chemistry, and Maths for your exams.
Watch a detailed breakdown of how to create ray diagrams for a concave mirror. Our tutor explains each case, from an object at infinity to one between the pole and focus, and covers the practical uses of concave mirrors.
This lecture is an introduction to the fundamentals of mirrors for Class 10 Physics. We cover the difference between plane and spherical mirrors, key terms like center of curvature and focus, and the rules for making ray diagrams.
Master trigonometry with this foundational lesson for Class 10. We cover all the essential formulas, from basic ratios like sin, cos, and tan to the three core trigonometric identities you need to know for your exams.
This one-minute summary covers all the important formulas from the Light chapter. We quickly revise the mirror formula, lens formula, refractive index, power of a lens, and magnification for last-minute preparation.
About this collection
The biggest mistake students make with ray diagrams or trigonometric identities is trying to memorize them instead of building them from scratch. In these lectures, I don't just solve problems on the board; I show you the rules for placing objects, measuring distances, and deriving formulas so you can tackle any board exam question without panic.
Building Concepts, Not Rattafication
When we look at the 'Light' chapter for Class 10, most students get stuck on ray diagrams because they try to remember the result rather than the logic. My whiteboard sessions focus on the 'why' behind the physics. Whether it is understanding why a concave mirror creates a magnified image for dentists or how to place your object at the center of curvature to get an exact, real, and inverted image, we walk through it step-by-step.
What You Will Find Here
These clips are direct pulls from my full classroom lectures. We don't skip steps.
- Physics: We break down ray diagrams, mirror formulas, and the rules of reflection. I teach you how to use your scale properly for C and F distances so your diagrams are accurate every time.
- Maths: Trigonometry is just ratios of sides. In these videos, I simplify sin, cos, and tan identities, showing you how they link back to a right-angled triangle, making it easier to solve problems during your exams.
Why Learn This Way?
I believe that a student understands better when they see a human teacher solving the problem in real-time, errors and all. If you are struggling with a specific concept from the NCERT book, these videos are meant to be your 24/7 tutor. If you need more than just a video, I offer personalized 1-on-1 home tuitions in Delhi NCR and online sessions across India, where we can deep-dive into your specific doubts until you get it right.
EduGyani
I'm Karan Jha, and at EduGyani, I believe the real support for a student comes from the teacher who stays up to solve doubts, not just the school. I focus on breaking down concepts with simple tricks and whiteboard visuals because I know that once you understand the logic, the marks follow naturally.
