Explanation:</h2>
For lenses in an achromatic combination, the following condition holds, assuming the two lenses are of the same materials;
d =
---------(i)
Where;
d= distance between lenses
f₁ = focal length of the first lens
f₂ = focal length of the second lens
From the question;
f₁ = 4.5cm
f₂ = 1.5cm
Substitute these values into equation (i) as follows;
d = ![\frac{4.5+1.5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B4.5%2B1.5%7D%7B2%7D)
d = ![\frac{6.0}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B6.0%7D%7B2%7D)
d = 3.0cm
Therefore, the distance between the two lenses is 3.0cm
