Question

If the magnitude of dispersive power of 2 lenses are 0.024 and 0.036 then their focal lengths will be for aberration free combination

Answer 1

Answer:

Explanation:

Given If the magnitude of dispersive power of 2 lenses are 0.024 and 0.036 then their focal lengths will be for aberration free combination

The relation between aberration free focal length along with disperse powers is given by f1/f2 = - w1/w2

= 0.024 /0.036 24/36 = 2/3

Now we can write in terms of f1/f2 = - 30/45 = - 2/3

Now we can say as focal length will be equal to 30 cm and – 45 cm.

The relation between aberration free focal length along with disperse powers is given by f1/f2 = - w1/w2

= 0.024 /0.036 24/36 = 2/3

Now we can write in terms of f1/f2 = - 30/45 = - 2/3

Now we can say as focal length will be equal to 30 cm and – 45 cm.
