The lens equation is 1/f=1/p+1/q , where f is the focal length of the lens, p is the distance of the object from the lens, and q is the distance of the image from the lens. the formula to find q is:
a. q=pf/p-f
b. q=p-f/pf
c. q=pf/p+f

Step-by-step explanation:

The lens equation is .

To solve this formula for , we need to multiply each term by .

.

We cancel out the common factors to get;

.

We group the terms in q on one side of the equation;

.

Factor q.

.

Divide both sides by

The correct answer is A

77

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
