In a simple microscope of focal length `5 cm` final image is formed at `D`, then its magnification will be

What is the magnifying power of a simple microscope of focal length 5 cm, if the image is formed at the distance of distinct vision ?

A simple microscope with a focal length 5 cm forms an image at the near point of the eye. Find its magnification.

In a terrestrial telescope, the focal length of objective is 90cm , of inverting lens is 5 cm and of eye lens is 6 cm . If the final image is at 30cm , then the magnification will be the final image is at 30cm, then the magnification will be

An object is seen through a simple microscope of focal length 20 cm. Find the angular magnification produced, if the image is formed at 30 cm from the lens.

An object is seen through a simple microscope of focal length 20 cm. Find the angular magnification produced, if the image is formed at 30 cm from the lens.

An object is seen through a simple microscope of focal length 12 cm. Find the angular magnification produced if the image is formed at the near point of the eye which is 25 cm away from it.

An object is seen through a simple microscope of focal length 12 cm. Find the angular magnification produced if the image is formed at the near point of the eye which is 25 cm away from it.

Draw a ray diagram to show the working of a compound microscope. Deduce an expression for the total magnification the final image is formed at the near point. In a compound microscope , an object is placed at a distance of 1.5 cm from the objective of focal length 1.25cm. if the eye piece has a focal length of 5 cm and the final image is formed at the near point, estimate the magnifying the power of the microscope.

In a terrestrial telescope, the focal length of objective is 90cm and of eye lens is 6 cm . If the final image is at 30cm , then the magnification will be
