Follow instructions and answer all questions for each problem: The use of a lens in a certain situation is described by the equation 1/p + 1/-3.50p = 1/7.50cm Determine (a) the image distance. Hint: p is the object distance. Solve p first, and then find the image distance Use a ray diagram to obtain a description of the image. Determine whether it is a virtual image or a real one. Repeat (a) and (b) for the following equation: 1/p + 1/5.00p = 1/7.50cm
