A telescope is used to resolve two stars separated by `4.6 xx 10^(-6)` radian.If the wavelength fo light used is `5,460 overset @A`,what shold be the aperture of the objective of the telescope?

In Young' double slit experiment, the expriment, the angular width of a fringe formed on a distant screen is 0.5^@ . The wavelength of light used is 6000 overset@A . What is the spacing between the slits?

In Young' double slit experiment, the expriment, the angular width of a fringe formed on a distant screen is 0.5^@ . The wavelength of light used is 6000 overset@A . What is the spacing between the slits?

The diameter of the objective lens of the telescoe is 5 m and waveelnegth of light is 6,000 overset @A .The limit of resolution of this telescope is:

A telescope has objective lens of focal length 15m. If this telescope is used to view the moon, what is the diameter of the image of the moon formed by the objective lens? The diameter of the moon is 3.48 xx 10^6m , and the radius of lunar orbit is 3.8 xx 10^8m .

A small telescope has an objective lens of focal length 140 cm and an eyepiece of focal length 5.0 cm. (A) If this telescope is used to view a 100 m tall tower 3 km away, what is the height of the image of the tower formed by the objective lens? (B) What is the height of the final image of the tower if it is formed at 25 cm?

In a Young's double slit experiment,the slits are 1.5 mm apart.When the slits are illuminated by a monochromatic source and the screen is kept 1 m aprat from the slits,width of 10 fringes is measured as 3.93 mm.Calculate the wavelength of light used.What will be the width of 10 figes,when the distance between the slits and the screen is increased by 0.5 m?The source of light used remains the same.

A telescope has an objective lens of 10 cm diameter and is situated at a distance of 1 km from two objects.The can be resolved by the telescope, when the mean wavelength of light is 5,000 overset @A ,is of the order of

A small telescope has an objective lens of focal length 140 cm and an eyepiece of focal length 5.0 cm. (A) what is the separation between the objective lens and the eyepiece? (B) If this telescope is used to view a 100 m tall tower 3 km away, what is the height of the image of the tower formed by the objective lens?

Young's double - slit experiment for interference is performed with two slits 3xx 10^(-3) m apart and light of wavelength 6,600 overset @A . If the screen is 1 m away from the slits,find out the position of the fourth dark fringe.

A telescope has an objective of diameter of 60 cm. The focal lengths of the objective and eye piece are 2.0 m and 1.0 cm respectively. The telescope is directed to view two distant almost point sources of light (e.g. two stars of a binary). The sources are at roughly the same distance (=10^4 light years) along the line of sight but separated transverse to the line of sight by a distnace of 10^10 m . what will the telescope resolve the two objects i.e. will it see two distinct stars?
