A telescope is used to observe two distant point sources transversely 2.50 {\rm m}apart with light of wavelength 600 {\rm nm} .The objective of the telescope is covered with a slit of width0.350 {\rm mm} . What is the maximum distance in meters at which the two sources maybe distinguished if the resolution is diffraction limited and Rayleigh's criterion is used?
Assume the wheel has a constant negative angular acceleration of magnitude 2.50 rad/s2. Explain through how many radians has the wheel turned during the interval found in (a) which is 4.98?
Note down that since each oscillator is attached to two "springs", and each "spring" is half the length of the interatomic bond, the effective interatomic spring stiffness for one of these oscillators is times estimated value given above.
