An object is located to the left of a convex lens whose focal length is f=34...

An object is located to the left of a convex lens whose focal length is f=34 cm. The magnification (m) produced by the lens is 4.0. Find an expression for magnification in terms of “f” and object distance (do). To increase the magnification to 5.0, calculate the distance through which the object should be moved. Also explain your result with free hand ray diagram. At what position of the object the magnification becomes infinity?

When an object is placed at a distance greater than the focal length but less than twice the focal length from a convex lense

When an object is placed at a distance greater than the focal length but less than twice the focal length from a convex lense the image is diminished.the image is virtual.All of the other choices are not correct.the image is inverted.the image is formed on the same side as theobject.For an object placed in front of a concave lense,the image is always realthe image may be erect or inverted.the image is formed on the other side of thelense.the image may be...

A magnifying glass is a single convex lens with a focal length of f = +9.50 cm. (Assume the person using the magnifying glass has a near point of 25 cm and the magnifying glass is directly in front of the person's eyes.) (a) What is the angular magnification when this lens forms a (virtual) image at ??? How far from the object should the lens be held? (b) What is the angular magnification when this lens forms a (virtual)...

1. Consider a convex lens with a focal length of 5.50 cm. An object is located at 13.50 cm. The object is 6.00 cm tall. Draw the ray diagram to scale. Determine the image distance, the height of the image, the magnification and the characteristices of the image. Pay attention to the sign conventions and units. 2.

A concave lens has a focal length of magnitude 10 cm. It is placed a distance of 25 cm from a concave mirror with a focal length of magnitude 15 cm. An object is set a distance of 22 cm in front of the lens. The observer is at the same location as the object, so the light from the object goes through the lens, reflects off the mirror, and comes back through the lens to the observer. Draw the...
