Write me a code to program for focal length of a lens and the other steps required given the following:
Program for focal length of a lens | Function to determine the focal length of a lens.
Variable to store the distance between the lens and the image.
Variable to store the distance between the lens and the object"
Solution in Python:
assistant
#Here is code to program for focal length of a lens and the other steps required.
 def focal_length ( image_distance , object_distance )
	: return 1 / ( ( 1 / image_distance ) + ( 1 / object_distance ) )
image_distance = 2
object_distance = 50
result = focal_length ( image_distance , object_distance )
print ( " Focal ▁ length ▁ of ▁ a ▁ lens ▁ is ▁ " , result , " ▁ units . " )
