A lens has a magnification of +2.0 and if the focal length is +10 find the impage position and the object position.
The type of lens is a diverging lens, but how do i find the di and the do if nothing else is given?
Isn't M= -di/do ?
To find the image position (di) and the object position (do) of a lens, you need to use the lens formula:
1/f = 1/di - 1/do
where:
f is the focal length of the lens,
di is the image distance or position, and
do is the object distance or position.
In this case, you are given the focal length (f) as +10, and you know that the lens is a diverging lens.
Since the lens is diverging, the focal length (f) will be negative (-10, rather than +10), as divergence is associated with negative focal lengths.
Now, let's find the di and do using the lens formula:
1/f = 1/di - 1/do
Substituting the given values, we get:
1/-10 = 1/di - 1/do
To solve for di and do, we need another equation or value. Without additional information about the object or image (such as the height or the distance between them), we cannot determine the specific values of di and do.
Therefore, we would need additional data or information to find the di and do values.
