A concave mirror is half dipped in water.Focal length of portion of mirror in the air is f1 and focal length of mirror in water is f2,then (Take refractive index of water=4/3)
options: 1)f1 greater than f2 2)f1 less than f2 3)f1=f2 4)f1 greater than equal to 4/3f2
Dear Student,
Please find below the solution to the asked query:
There will be no difference in the focal lengths of the two portions. Thus, f1 = f2. Option (3) is correct.
Hope this information will clear your doubts about (Ray optics).
