Answer:
The length and the magnification of this telescope are 41 cm and 0.108.
Explanation:
Given that,
Focal length of first lens f= 4.0 cm
Focal length of other lens f'= 37 cm
We need to calculate the length of the telescope
Using formula of length
[tex]L=f+f'[/tex]
Put the value into the formula
[tex]L=4+37=41 cm[/tex]
We need to calculate the magnification of the telescope
Using formula of the magnification
[tex]m=\dfrac{f}{f'}[/tex]
Put the value into the formula
[tex]m=\dfrac{4}{37}[/tex]
[tex]m=0.108[/tex]
Hence, The length and the magnification of this telescope are 41 cm and 0.108.
