CBSE Class 10 - Spherical Lens and its Power Videos
Power and nature of a lens
This video explains the relation between the focal length and power of lens and identifying the nature of lens based on the power of lens
- 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 *
