CBSE Class 10 - Spherical Lens and its Power Videos
Power and Nature of Lens
This video explains the power of lens, its SI unit and shows how to identify the nature and power of lens based upon its focal length.
- image 1 cm long of object is formed on a screen by convex lens keeping the object and the screen is the lens is moved until a s image is formed on the screen if the image of 0.75 cm long what is the lenght of the object
- Focal Length of lens A is +10cm & lens B is -5cm. Find combined power
- why are telescopes launched in space ? explain in brife about the hubble telescope launched in space
- drop of water bheaves like a
- what is lens
- power of a lens is found to be + 2.5Diopter what kind of lens is it
- power of a lens is found to be + 2.5 Diopter what kind of lens is it
- The radius of curvature of two faces of double convex lens are 10cm,15cm and its focal length is 12cm. Then determine refractive index of lens
- why does in case of hypermetropia using a convex lens doesnot affect our far view
- If a spherical lens has a power of, – 0.25 D, the focal length of this lens will be *
