In the following problem, I am having trouble understanding the components.
- The image of a man just covers the length of a 5cm plane mirror when the mirror is held vertically 30cm from the eye. The tree is 100m from the mirror. What is the height?
* To find the height you would use hi/ho = -i/o
and you would also use 1/i + 1/o = 1/f to find these components. But I can not understand what the measurements mean in the question.
The object would be the tree, 100m from the mirror.
What are the other two (5cm and 30 cm)
Can I use the hi/ho formula directly for this problem?
