A focal length is the distance between the center of a lens or curved mirror and it's focus.

A focal length is a otpical system thst measure how strongly the system converges or diverges light.

Focal length

# data[].attributes.body
Focal length is the measurement of how strong a camera diverts light

# data[].attributes.body
focal length  will determine if the angle of view is narrow  or wide depending on if the focal length is set longer or shorter.

Focal Length is a system that measurement of strength in system that converges or diverges light.

# data[].attributes.body
Focal length is a system that measures how strong the system's light coverage is

A focal is a system that mesasures how strongly the system cinverges or diverges.

# data[].attributes.body
the focal length is a system that measure of how strongly can the system converges or diverges light

# data[].attributes.body
A calculation of the  optical distance of where all light rays converge inside the lens to the image center of the camera.

Focal length is the distance between the lens and the focal point when the lens is set at infinity.

Focal length is a measurement of how strongly the system converges or diverges light.

# data[].attributes.body
A focal length is a measure of how strongly the optical system converges or diverges light.

# data[].attributes.body
A focal length is the distance between the center of a lens or curved mirror and its focus.

# data[].attributes.body
Focal length is a measure on how the lens work and how strong the camera is converges and to diverges light.

# data[].attributes.body
It is the focal length. The lens define how much light goes into the picture sensor. The length is measured in mm and its how much the coverage is.

# data[].attributes.body
Focal length is a measurement of how strong the camera convergence is. It also indicates how much the view will be captured. Also magnification and how the view will be like.

Focal length is a optical system that measure how strongly the system converges or diverges light

# data[].attributes.body
The focal length of an optical system is a measure of how strongly the system converges or diverges light, it is the inverse of the system's optical power.
