Resolving power is defined as the ability of a microscope or telescope to distinguish two close together images as being separate. An example of resolving power is how well a telescope can show two stars as being separate stars. YourDictionary definition and usage example.

twinkle1125: thnx but i wanted the formula...
madhav3213: plz mark as brainliest
nanu95star89: please mark brain list
madhav3213: Resolving power =​ 2usin@ / 1.22λ, here u = refractive index, @ = angle subtended by object on objective, lambda is wavelength.....
Limit of resolution is just reciprocal of Resolving power
madhav3213: formula
twinkle1125: ok
twinkle1125: plzz follow me
twinkle1125: madhav3213 u also follow me
twinkle1125: i marked u as brainlist
twinkle1125: thnx

…be capable of a seven-point resolution of the image, which raises the problem of incorporating multiple inverted images into a single erect image that the ordinary apposition eye avoids. In 1967 German biologist Kuno Kirschfeld showed that the angles between the individual rhabdomeres in one ommatidium are the same as…

The number of ommatidia in apposition eyes varies from a handful, as in primitive wingless insects and some ants, to as many as 30,000 in each eye of some dragonflies (order Odonata). The housefly has 3,000 ommatidia per eye, and the vinegar fly (or…

De Broglie derived the formula for their wavelength, which showed that, for example, for electrons accelerated by 60,000 volts…

Resolving power is another important feature of a telescope. This is the ability of the instrument to distinguish clearly between two points whose angular separation is less than the smallest angle that the observer’s eye can resolve. The resolving power of a telescope can be…
