Image Formation by Spherical Mirror: Concave Mirror

CBSE Class 10 Physics Chapter 10: Light – Reflection and Refraction. How are the images formed by the concave mirror? How can we locate the image formed by a concave mirror for different positions of the object? Are the images real or virtual? Are they enlarged, diminished or have the same size? This is demonstrated with the help of an activity with the help of a screen and candle flame.  

Image Formation by Lenses: Convex Lens

CBSE Class 10 Physics Chapter 10: Light – Reflection and Refraction. How are the images formed by the convex lens? How can we locate the image formed by a convex lens for different positions of the object? Are the images real or virtual? Are they enlarged, diminished or have the same size? This is demonstrated with the help of an activity with the help of a screen and candle flame.  

The Human Eye

CBSE Class 10 Physics Chapter 11: Human Eye and the Colorful World. The human eye is one of the most valuable and sensitive sense organs. It enables us to see the wonderful world and the colours around us. The human eye works like a camera. This is explained with detailed information.  

Power of Accommodation

CBSE Class 10 Physics Chapter 11: Human Eye and the Colorful World. The ability of the eye lens to adjust its focal length is called accommodation. The detailed working of accommodation of human eye to see objects at different distances is explained.  

Scattering of Light in Colloidal Solution

CBSE Class 10 Physics Chapter 11: Human Eye and the Colorful World. Have you seen the sky and the Sun at sunset or sunrise? Have you wondered as to why the Sun and the surrounding sky appear red? This is explained with an activity to understand the blue colour of the sky and the reddish appearance of the Sun at the sunrise or sunset.  

Electric Circuit Diagram

CBSE Class 10 Physics Chapter 12: Electricity. An electric circuit consists of various components like battery, resistor, rheostat, voltmeter etc. How are these represented in an electric circuit diagram? This is explained in the video.  

Ohm’s Law

CBSE Class 10 Physics Chapter 12: Electricity. What is Ohm’s law? How does the relationship between voltage and current is derived from the ohms law? This is demonstrated by an activity.  

Resistors in Series

CBSE Class 10 Physics Chapter 12: Electricity. What happens to the value of current and voltage when a number of resistors are connected in series in a circuit? This is explained with a demonstrated in the video.
