The focal length of a concave lens is 10cm. what should be the object distance in order that the image is 1/5th of size of the object. where is the image? What is its lateral magnification?
Answers
Answer:
Explanation:
3 moment of inertia
Answer:
Lens magnification can be find using m 1 = - 0.2 First lens has magnification of – 0.2 Image magnification in terms of object and image height can be write First lens has magnification of – 0.2, the image is inverted and is 0.2 times of original height.
Two converging lenses, with the focal length f 1 = 10 cm and f 2 = 15 cm are placed 40 cm apart, as shown on the figure. An object is placed 60 cm in front of the first lens as show in second figure.
A convex mirror and a diverging lens always do this. A concave mirror and a converging lens can produce an upright image and and image reduced in size, but never one which is both upright AND reduced in size.
