Question

an object is placed at a distance of 30cm in front of a convex lens of focal length 20 cm find the magnification of image​

Answer 1

Answer:

Here,

Here,Image distance=v=20cm,

Here,Image distance=v=20cm,Object distance=u=−30cm,

Here,Image distance=v=20cm,Object distance=u=−30cm,Lens equation is given by,

Here,Image distance=v=20cm,Object distance=u=−30cm,Lens equation is given by,v

Here,Image distance=v=20cm,Object distance=u=−30cm,Lens equation is given by,v1

Here,Image distance=v=20cm,Object distance=u=−30cm,Lens equation is given by,v1

Here,Image distance=v=20cm,Object distance=u=−30cm,Lens equation is given by,v1 −

Here,Image distance=v=20cm,Object distance=u=−30cm,Lens equation is given by,v1 − u

Here,Image distance=v=20cm,Object distance=u=−30cm,Lens equation is given by,v1 − u1

Here,Image distance=v=20cm,Object distance=u=−30cm,Lens equation is given by,v1 − u1

Here,Image distance=v=20cm,Object distance=u=−30cm,Lens equation is given by,v1 − u1 =

Here,Image distance=v=20cm,Object distance=u=−30cm,Lens equation is given by,v1 − u1 = f

Here,Image distance=v=20cm,Object distance=u=−30cm,Lens equation is given by,v1 − u1 = f1
