A microscope has an objective lens with a focal length of 19.5 mm and an eyepiece with a focal length of 6.2 mm. With the length of the barrel set an 33.0 cm, the diameter of a red blood cell’s image subtends an angle of 1.2 milli-radians with the eye. The final image distance is 29.0 cm from the eyepiece. (a) What is the length of the image of the of the cell produced by the eyepiece? (b) Using the...

A concave lens has a focal length of -36 cm. Find the image distance and magnification that results when an object is placed 19 cm in front of the lens. (Use the proper sign convention for both quantities.) When an object is located 61 cm to the left of a lens, the image is formed 25 cm to the right of the lens. What is the focal length of the lens? An object with a height of 2.22 cm is...
