Answer:
= 2.83
Explanation:
F number (N) is given by the formula;
F- number = f/D
where f = focal length of lens and D = diameter of the aperture
Therefore;
F number = 17 cm/6 cm
= 2.83
The number of the television camera lens with focal length 17 cm and lens diameter 6.0 meter is 2.83.
What is the focal length of the lens?
The focal length of the lens is the length of the distance between the middle of the lens to the focal point.
It can be find out using the following formula as,
[tex]f=d\times n[/tex]
Here, (c)is the diameter the lens and, (n) is the number of the lens. This formula can be written as,
[tex]n=\dfrac{f}{d}[/tex]
The television camera lens has a 17-cm focal length and a lens diameter of 6.0 cm. Thus put this values in the above formula as,
[tex]n=\dfrac{17}{6}\\n=2.83[/tex]
Thus, the number of the television camera lens with focal length 17 cm and lens diameter 6.0 meter is 2.83.
