Which quantity associated with light wve sets the limit of ability to distinguish very close objects?

A light of wavelength 3200overset(@)A is coming from a star. What is the limit of resolution of a telelscope whose objective has a diameter of 86 inch?

Which quantity is fixed on object on object which moves in a horizontal circle at constant speed

Which of the following statements are true? If false, correct them: It is very easy to establish the essentiality of micronutrients because they are required only in trace quantities.

A narrow beam of white light passes through a triangular glass prism and gets split up into seven colours marked 1 to 7. Which two positions correspond closely to the colour of: 'danger' or 'stop signal lights'?

When white light travels through glass the refractive index mu=(velocity of light in air/velocity of light in glass) is found to very with waveless as mu=A+B/lambda^2 where A and B are constants. Using the principle of homogeneity of dimensions, determine the SI unit in which A and B must be expressed.
