The Square Kilometers Array (SKA) is a set of thousands of radio dipole antennae and telescope dishes that is planned to be build, starting in 2016. It is to spread out over a distance of more then 3000 km. The combined signals will have a resolving power equivalent to that of an aperture of approximately 1000 km (a) If the detector are turned to a frequency of , what is the angular resolution of SKA? (b) Clouds of interstellar hydrogen radiate at a frequency used in part (a). What must be the separation distance of two clouds at the center of galaxy, 26000 light years away, if they are to be resolved?
Compton effect
The incoming photons' energy must be in the range of an X-ray frequency to generate the Compton effect. The electron does not lose enough energy that reduces the wavelength of scattered photons towards the visible spectrum. As a result, with visible lights, the Compton effect is missing.
Recoil Velocity
The amount of backward thrust or force experienced by a person when he/she shoots a gun in the forward direction is called recoil velocity. This phenomenon always follows the law of conservation of linear momentum.
